Abstract
An improved tungsten carbide powder comprises (W,Cr)C solid solution phase for oxidation resistance at high temperatures. The improved tungsten carbide powders may be formed by carburizing a mixture of tungsten powder, carbon powder, and CrOpowder. The tungsten carbide powder herein may be used to form ready-to-press (RTP) or grade powders. These RTP may be used to form articles, including articles that require excellent oxidation resistance at high temperature. One such component is a seal ring for a liquid battery.
