METHOD OF PRODUCTION OF ZIRCONIUM CARBIDE Russian patent published in 2015 - IPC C01B31/30 C01G25/00 B82B1/00

Abstract RU 2566420 C1

FIELD: metallurgy.

SUBSTANCE: method means rubbing through sieve of the charge having stoichiometric composition out of zirconium dioxide and carbon material with further heating in electric resistance furnace with graphite tube. At that heating is performed at temperature 1800-1900°C with holding at this temperature for 20-25 minutes, specific surface area of the carbon material is 138-160 m²/g, and nanofibre carbon is used as carbon material.

EFFECT: reduced power consumption during zirconium carbide production.
