Description
Technical field
The present invention relates to the method for a kind of solid-state reaction at room temperature synthesis bismuth phosphate nanoparticle.
Background technology
Bismuth phosphate (BiPO
4) there are three kinds of crystal formations: monoclinic phase, monoclinic phase monazite structure and six side's phase structures.In three kinds of crystal formations, positively charged ion Bi
3+eight-coordinate structure is formed, P with Sauerstoffatom
5+with Sauerstoffatom four-coordination, Bi and P atomic building oxygen polyhedron is spaced, and its ratio is 1:1.According to the report of the people such as Slater, BiPO
