· JVASP-114175· CaO3

CaO3 is a calcium oxide ceramic compound that exists primarily in research and specialized contexts, as it is not a stable phase under normal conditions—calcium typically forms CaO (lime) or CaCO3 (limestone) in industrial applications. This material belongs to the family of alkaline earth oxide ceramics and may be studied for high-temperature applications, refractory systems, or as a precursor phase in calcium-based ceramic processing. Engineers would consider this compound for applications requiring high-temperature stability and rigid ceramic behavior, though its practical availability and phase stability should be verified against project requirements.
