· LaPO4

Lanthanum phosphate (LaPO₄) is a rare-earth ceramic compound that combines a lanthanide element with phosphate chemistry, belonging to the family of rare-earth phosphates used in high-temperature and specialized applications. This material is primarily investigated for thermal barrier coatings, nuclear waste immobilization, and high-temperature structural applications where chemical stability and thermal properties are critical. LaPO₄ is notable for its resistance to thermal shock and chemical attack compared to conventional ceramics, making it attractive for extreme-environment engineering and nuclear fuel encapsulation research.
