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

Structure

[edit]

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

Properties

[edit]

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]
