ABSTRACT:
The object of the invention is to provide a zinc antimonate anhydride and a production method thereof. The invention relates to a particle having a ZnO/Sb.sub.2 O.sub.5 molar ratio in a range of from 0.8 to 1.2, a crystal structure of zinc antimonate anhydride (Znsb.sub.2 O.sub.6), and a primary particle size in a range of from 5 to 500 nm. The production method of these particles comprises the steps of mixing a zinc compound with a colloidal antimony oxide at a ZnO/Sb.sub.2 O.sub.5 molar rate in a range of from 0.8 to 1.2, followed by calcining the mixture within a temperature range of from 500.degree. to 1100.degree. C. The particles of this invention are applicable as a flame retardant for plastics, a smoke suppressant, antistatic agent for plastics and glasses, and resistor.
