RECEIVING ULTRADISPERSE COBALT BY REDUCTION OF CRYSTAL COBALT CARBONATE
Abstract
Оne of the chemical methods of receiving an ultradisperse powder of cobalt by reduction of crystal salt of cobalt carbonate
with hydrazine water solution is considered in the paper. Particles of the various sizes and forms have been received.
The temperature and concentration factors influencing dimensional characteristics of metal cobalt are studied.
