METHOD OF PRODUCING ZINC OXIDE POWDER Russian patent published in 2012 - IPC C01G9/02 

Abstract RU 2450972 C1

FIELD: chemistry.

SUBSTANCE: method of producing zinc oxide powder by oxidising zinc with oxygen while heating, where zinc metal first undergoes distillation at temperature lower than boiling point in a stream of an inert gas; the obtained powder is oxidised in a revolving reactor with a controlled atmosphere at temperature lower than the boiling point of zinc.

EFFECT: invention enables to obtain zinc oxide powder containing less impurities than the starting metal using commercial-grade zinc metal and industrial oxygen as starting materials.
