Barium phosphate (Ba₃(PO₄)₂) is an inorganic phosphate of barium. It is white, odorless and insoluble in water.^[1]

Structure

The crystal structure is rhombohedral with a space group of R3m, the same as in strontium phosphate.^[2]

Properties

Barium phosphate exhibits properties such as high refractive index, low melting and low glass transition temperature, high transparency to ultraviolet light, and high thermal expansion coefficient.^[3]
