· ScAsO4

ScAsO4 is a scandium arsenate ceramic compound belonging to the family of metal arsenate ceramics, which are primarily investigated in advanced materials research rather than established commercial production. This material is of interest in specialized applications requiring high stiffness and thermal stability, particularly in research contexts exploring rare-earth and transition-metal arsenate ceramics for functional and structural applications. While not widely adopted in mainstream engineering, arsenate ceramics have potential in high-temperature environments, nuclear applications, and materials with tailored dielectric or thermal properties where chemical stability against specific environments is advantageous.
