description The invention relates to a method for preparing hafnium carbide ceramic by a precursor conversion method and hafnium carbide of a ceramic block material. The method comprises the following steps: preparing a hafnium carbide precursor by a gel-sol method, and reacting and sintering the hafnium carbide precursor to generate hafnium carbide. The hafnium carbide precursor is prepared by mixing hafnium hydroxide gel, polyvinyl alcohol resin and ethylene glycol and then curing and drying the mixture. And carrying out thermal treatment reaction sintering to prepare the hafnium carbide ceramic. A hafnium carbide precursor is prepared by mixing hafnium hydroxide gel, polyvinyl alcohol resin and ethylene glycol and then curing and drying the mixture, the hafnium carbide ceramic is prepared by heat treatment reaction sintering of the polyvinyl alcohol resin, ethylene glycol and hafnium hydroxide gel, and a hafnium carbide ceramic block finished product is obtained. The raw materials are simple and easy to obtain, safe a
