· AlAsO4

Aluminum arsenate (AlAsO4) is an inorganic ceramic compound belonging to the phosphate/arsenate family of ceramics. While not a widely commercialized engineering material, it is primarily of research interest for its potential in specialized applications requiring arsenic-based ceramics, particularly in materials science studies of mixed-metal oxyanion systems. The material's significance lies in academic investigations of ceramic phase chemistry and potential niche applications in radiation-resistant ceramics or specific refractory environments where arsenate phases provide advantages over conventional oxides.
