CK32 compound carbide with low oxygen content and low free carbon and preparation method of CK32 compound carbide

The invention belongs to the technical field of powder metallurgy, and particularly relates to a CK32 compound carbide with low oxygen content and low free carbon and a preparation method thereof.The preparation method comprises the steps that a tungsten source, a titanium source and a carbon source are taken and subjected to wet grinding to obtain a mixture, the mixture obtained through wet grinding is dried, the dried mixture is subjected to compression molding and then calcined in an argon environment, crushed and sieved, and screen underflow is taken to obtain the CK32 compound carbide with the low oxygen content and the low free carbon. The Fisher particle size of the CK32 compound carbide with the low oxygen content and the low free carbon is 2.2-2.7 microns, the total carbon content is 11.2-11.4 wt%, the content of free carbon Cf is smaller than or equal to 0.03 wt%, and the content of O is smaller than or equal to 0.04 wt%. 本发明属于粉末冶金技术领域，具体涉及一种低氧含量低游离碳的CK32复式碳化物及其制备方法，取钨源、钛源、碳源湿磨得到混合料，将湿磨得到的混合料进行干燥，将干
