· ScPO4

Scandium phosphate (ScPO4) is a ceramic compound belonging to the phosphate family, characterized by a crystal structure that confers high stiffness and thermal stability. While primarily a research material rather than a commodity engineering ceramic, it is investigated for applications requiring chemically stable, high-modulus ceramics in extreme environments, particularly as an alternative to traditional oxides where phosphate chemistry offers advantages in thermal or chemical resistance.
