· JVASP-10691· CeSiO4

Cerium silicate (CeSiO₄) is a rare-earth ceramic compound combining cerium oxide with silica, belonging to the family of rare-earth silicates studied for high-temperature and radiation-resistant applications. While not widely commercialized as a primary structural material, this ceramic is investigated in research and development contexts for aerospace, nuclear, and advanced thermal barrier applications where rare-earth elements provide superior oxidation resistance and thermal stability compared to conventional silicates. Its rare-earth dopant characteristics make it of particular interest for specialized environments requiring resistance to neutron irradiation, thermal cycling, or aggressive chemical attack.
