Title:

PRODUCTION OF NICKEL OXIDE POWDER

Document Type and Number:

Japanese Patent JPH0710544

Kind Code:

A

Abstract:

PURPOSE: To obtain high purity nickel oxide powder having a small particle diameter by heat-treating nickel nitrate or nickel nitrate hydrate in the air or in a neutral atmosphere.

CONSTITUTION: Nickel nitrate hexahydrate is heated at 20-40°C/min rate and heat-treated at ≥500°C in the air for about 1hr to obtain a thermally decomposed product. This product is recovered and the objective nickel oxide powder having ≥99.9wt.% purity and a small particle diameter is produced.
