ceramic

· JVASP-49229· Ca4Al6TeO12

Ca4Al6TeO12 is a complex oxide ceramic compound containing calcium, aluminum, and tellurium. This material belongs to the family of mixed-metal tellurate ceramics, which are primarily of research interest for their potential in optical, photocatalytic, and high-temperature applications. The material is not widely established in mainstream industrial production; its development is driven by investigations into novel ceramic compositions for specialized functions such as photocatalysis, radiation shielding, or advanced refractory uses where tellurium-containing phases offer unique electronic or thermal properties.
