GASKARBURIERUNGSVERFAHREN FOR PRODUCING PURE WC-POWDER

摘要

The invention relates to a Gaskarburierungsverfahren for producing fine-grained WC powder in equipment for fluidized bed reaction, starting from flowable tungsten or wolframoxidhaltigem powder of mean grain size d`50 10 microns in a single process step in specific process temperature and process gas mixture with a carbon activity always 1 and close as possible to 1. The process is suitable for industrial scale a particularly economical WC production.
