METHOD FOR INCREASING OF ZINC OXIDE POWDER SPECIFIC SURFACE Russian patent published in 2005 - IPC

Abstract RU 2247074 C2

FIELD: inorganic powder material technology, in particular zinc oxide.

SUBSTANCE: zinc oxide is treated with ammonium carbonate followed by heat treatment of obtained product. Treatment of zinc oxide with ammonium carbonate is carried out by grinding of dry reagent in mass ratio of (1-5):1 or with 25-100 g/l ammonium carbonate solution in mass ratio of (2.5-10):1. Heat treatment is carried out at 180-200⁰C.

EFFECT: zinc oxide with increased specific surface from 5-15 m*992/g to 25-50 m*992/g.
