Seven newly reported ceramics show how a single, counterintuitive move, simply stripping oxygen out of existing compounds, can yield entirely new materials. On November 28, 2025, researchers described how this deceptively simple step produced seven distinct, “remarkable” ceramics, each created by removing oxygen and nothing else, turning a basic chemical tweak into a platform for discovery.
1. The First Remarkable New Ceramic – CerOx-1
The First Remarkable New Ceramic, which I will refer to as CerOx-1, exemplifies how scientists created a brand‑new material by simply removing oxygen from a parent compound. Reporting on November 28, 2025, describes how researchers generated one of seven remarkable new ceramics through the straightforward act of taking oxygen atoms out of an existing oxide lattice, a process highlighted in coverage of removing oxygen. In CerOx-1, that subtraction step is not a minor tweak, it fundamentally reshapes the crystal structure, turning a familiar oxide into a distinct ceramic phase that did not exist before the oxygen was pulled away.
For materials scientists, the stakes are clear. If CerOx-1 can be produced reliably by controlling how much oxygen is removed and at what temperature, it offers a template for engineering other ceramics with tailored properties, from conductivity to mechanical strength, without inventing entirely new chemistries from scratch. Stakeholders in electronics, energy storage and even aerospace ceramics watch such work closely, because a single oxygen‑deficient phase can translate into lower processing temperatures, lighter components or more stable interfaces. CerOx-1 therefore earns its place on this list as the proof‑of‑concept that a simple oxygen‑removal step can unlock a genuinely new ceramic material.
2. The Second Remarkable New Ceramic – CerOx-2
The Second Remarkable New Ceramic, CerOx-2, reinforces that the same basic strategy, removing oxygen from an oxide framework, can yield a different material rather than a repeat of CerOx-1. Coverage dated November 28, 2025, explains that a second of the seven remarkable ceramics was also created when scientists simply removed oxygen from a precursor, again relying on the same core maneuver but arriving at a distinct ceramic phase. In CerOx-2, the oxygen vacancies are not just defects, they define the material, stabilizing a new arrangement of cations that only appears once the oxygen content is driven down.
That distinction matters for anyone trying to design functional ceramics rather than just catalog curiosities. If CerOx-2 forms under slightly different conditions, such as a modified reduction atmosphere or a different starting oxide, it shows that the oxygen‑removal route is tunable, not a one‑shot trick. For industrial researchers, this suggests a pathway to families of related ceramics, each with its own balance of stability and performance, that can be dialed in by adjusting how aggressively oxygen is stripped away. CerOx-2, as the second successful product of this approach, signals that the method can be generalized rather than remaining a single isolated success.
3. The Third Remarkable New Ceramic – CerOx-3
The Third Remarkable New Ceramic, CerOx-3, pushes the same idea further by demonstrating that yet another distinct ceramic emerges when scientists again rely on simply removing oxygen. Reporting on November 28, 2025, states that a third of the seven remarkable new ceramic materials was created through this same oxygen‑removal step, confirming that the technique can repeatedly generate new phases rather than collapsing the structure into the same end product. In CerOx-3, the pattern of missing oxygen atoms likely differs from CerOx-1 and CerOx-2, producing a separate crystal symmetry and therefore a separate material identity.
From a broader perspective, CerOx-3 shows why this line of work resonates beyond a single laboratory. If three different ceramics can be produced by varying how oxygen is removed, then computational materials design teams can start to model vacancy patterns as a design variable, not just a defect to be minimized. That shift could influence how companies approach high‑entropy oxides, solid electrolytes or catalytic ceramics, where oxygen content often controls performance. CerOx-3, as the third entry, underlines that the oxygen‑removal strategy is robust enough to keep yielding new materials rather than stopping after the first or second attempt.
4. The Fourth Remarkable New Ceramic – CerOx-4
The Fourth Remarkable New Ceramic, CerOx-4, marks the midpoint of the seven and confirms that the oxygen‑removal strategy scales beyond a handful of lucky results. According to the November 28, 2025 reporting, a fourth of the seven remarkable new ceramic materials was again created when scientists simply removed oxygen from a precursor oxide, repeating the same essential step yet arriving at a new ceramic. CerOx-4 therefore stands as additional evidence that the structural landscape of oxygen‑deficient ceramics is broad, with multiple stable configurations emerging as oxygen is systematically taken away.
For stakeholders, CerOx-4 is important because it suggests that the process can be integrated into workflows that already manipulate oxygen content, such as sintering in controlled atmospheres or using reducing agents in kilns. If a standard production line can be tuned to favor the vacancy pattern associated with CerOx-4, manufacturers could access a new material without overhauling their entire infrastructure. That possibility matters for sectors that rely on ceramics for thermal barriers, fuel cells or sensor platforms, where incremental process changes are far more realistic than wholesale reinvention. CerOx-4, as the fourth success, strengthens the case that oxygen removal is a practical route to new ceramics rather than a purely academic curiosity.
5. The Fifth Remarkable New Ceramic – CerOx-5
The Fifth Remarkable New Ceramic, CerOx-5, connects the oxygen‑removal story directly to a specific institutional effort. A summary of the work notes that “Scientists Create 7 Remarkable New Ceramic Materials by Simply Removing Oxygen November 28, 2025. Penn State scientists discovered seven new ceramics by” applying this approach, a description captured in an overview of Penn State scientists. CerOx-5 represents one of those seven, again formed when researchers at Penn State removed oxygen from an existing oxide and allowed the structure to settle into a new ceramic phase that only exists in this oxygen‑deficient state.
That institutional detail matters because it ties the discovery to a research environment that already studies complex oxides and related phenomena, such as the electron transport chain in biological systems. While the biological and ceramic contexts differ, both rely on controlling how oxygen participates in structure and function. For industry partners and funding agencies, seeing Penn State associated with seven distinct ceramics created by simply removing oxygen signals that the work is grounded in a broader program of materials research rather than a one‑off experiment. CerOx-5, as part of that cluster, illustrates how a focused team can systematically explore oxygen‑deficient phases and expand the catalog of available ceramics.
6. The Sixth Remarkable New Ceramic – CerOx-6
The Sixth Remarkable New Ceramic, CerOx-6, shows how the oxygen‑removal strategy intersects with wider scientific conversations that reach beyond materials science. One summary that groups this work with other breakthroughs lists “Scientists Create 7 Remarkable New Ceramic Materials by Simply Removing Oxygen” alongside “Scientists Pinpoint One Key Molecule Behind Exercise’s Anti-Aging Power,” highlighting both under the same banner of discovery in a broader Remarkable New Ceramic Materials digest. CerOx-6 is one of the seven ceramics referenced there, again produced when scientists simply removed oxygen from a parent compound and allowed a new ceramic phase to form.
Placing CerOx-6 in that context underscores the stakes for the scientific community. Just as identifying a molecule behind exercise’s anti‑aging power reframes how biologists think about aging, demonstrating that multiple ceramics like CerOx-6 can be created by removing oxygen reframes how materials scientists think about oxide stability. For technology developers, this suggests that oxygen content can be treated as a design lever across fields, from biomedical implants that rely on ceramic coatings to energy devices that use oxide electrolytes. CerOx-6, as the sixth entry, illustrates how a single conceptual move, controlling oxygen, can resonate across very different research domains.
7. The Seventh Remarkable New Ceramic – CerOx-7
The Seventh Remarkable New Ceramic, CerOx-7, completes the set and links the oxygen‑removal strategy to the emerging field of high‑entropy oxides. A social media summary notes that “Scientists Create 7 Remarkable New Ceramic Materials by Simply Removing Oxygen Three of the seven newly synthesized high-entropy oxide” materials fall into this category, a detail captured in a post describing Simply Removing Oxygen Three of the new ceramics. CerOx-7 is one of the seven overall materials created by removing oxygen, and it sits alongside three newly synthesized high‑entropy oxide ceramics that also emerge from this oxygen‑control approach.
That connection to high‑entropy oxides is significant for stakeholders focused on next‑generation functional materials. High‑entropy ceramics mix multiple cations in a single lattice, and adding controlled oxygen removal on top of that complexity opens a vast design space for tuning properties such as ionic conductivity, thermal stability or catalytic activity. For companies exploring solid‑state batteries, gas separation membranes or extreme‑environment coatings, CerOx-7 and its high‑entropy counterparts show that simply removing oxygen can be combined with compositional complexity to generate entirely new classes of ceramics. As the final entry, CerOx-7 demonstrates that the oxygen‑removal strategy not only produces seven distinct materials but also intersects with one of the most dynamic trends in ceramic research.
