Under normal circumstances, the total carbon of tungsten carbide used for vacuum sintering in paraffin wax process is mainly determined by the compound oxygen content in the briquette before sintering.
One part of oxygen must be increased by 0.75 part of carbon, that is, WC total carbon = 6.13% + oxygen content% × 0.75 (assuming sintering The furnace is a neutral atmosphere. In fact, most vacuum furnaces use tungsten carbide for carburizing atmosphere and the total carbon is less than the calculated value).
