· JVASP-20841· CaTa4O11

CaTa4O11 is a calcium tantalum oxide ceramic compound belonging to the family of complex metal oxides. This material is primarily investigated in research contexts for high-temperature structural and functional applications, particularly where the chemical stability and refractory properties of tantalum-containing ceramics are advantageous. While not yet widely commercialized in mainstream engineering, materials in this class are of interest for specialized applications requiring resistance to thermal shock, chemical corrosion, and operation in demanding high-temperature environments.
