Abstract: The different growth unites of two polymorph antimony white were analyzed and determined according to the theoretical model of growth units with coordination polyhedron structure of anion, and the chajnge characteristic of the polymorph structure of antimony white prepared by hydrolysis was discussed in detail, and the polymorph control mechanism of antimony white powders prepared by hydrolysis was revealed.

Key words: coordination polyhedron structure of anion, antimony white, structure growth unit, polymorph
