properties

Bismuth (III) phosphate is a colorless solid. It is only slightly dissolved by water and dilute acids and is not hydrolyzed by boiling water. At room temperature it crystallizes anhydrous monoclinic with a crystal structure of the monazite type. In addition, there is also a monoclinic high-temperature form that forms from the low-temperature form from 750 ° C and a trigonal hydrate.

use

Used for coprecipitation of polonium , for studies of the relationship between plutonium radiation exposure and leukemia mortality and as a catalyst for the ammoxidation of propylene and the decomposition of dichlorodifluoromethane .
