Submicron Tungsten Carbide Powder Prepared with Ammonium Tungsten Bronze

Abstract:

Submicron tungsten carbide (WC) powder is obtained with ammonium tungsten bronze (ATB). The samples are characterized by laser particle size analyzer and scanning electron microscope (SEM). The analysis confirms that submicron tungsten powder is obtained with ATB through the deoxidation process in the hydrogen gas (Rate of purity: 99.99 %, dew point: -40 °C). And then submicron tungsten powder is carbonized in the hydrogen gas. The volume percent content of submicron WC powder between 0 μm and 1 μm is 83.7 %. Therefore, ATB is advantageous to prepare submicron WC powder via the conventional deoxidation and carbonization processes.
