Synthesis of Nanostructured WC Powders by Chemical Vapor Condensation Process

摘要

New approach to produce nanostructured WC powder by CVC(Chemical Vapor Condensation) process was made to improve the mechanical properties of advanced hardmetal. For powder preparation the easily decomposed precursor contained W components was used as starting materials. After synthesis of W-carbide powder from a precursor powder by CVC process, the powder size was about 10-20nm in diameter with less agglomeration, and of uniform particle size distribution.
