Aluminum phosphate (AlPO₄) is an inorganic ceramic compound belonging to the phosphate ceramic family, characterized by a crystalline structure that provides high hardness and thermal stability. It is used in specialized industrial applications including refractory materials, dental cements, abrasive compounds, and high-temperature insulators, where its chemical resistance and dimensional stability make it valuable in corrosive or thermally demanding environments. AlPO₄ is also of significant research interest as a host material for advanced ceramics and composites, particularly in applications requiring low thermal expansion and excellent chemical durability in acidic conditions.
