Method for preparing zirconium carbide wood ceramic
The invention discloses a method for preparing a zirconium carbide wood ceramic. The method comprises the following steps: (1) crushing a biomass material to be 50-800 meshes, adopting the hot-forming or rolling forming method to produce a blank body after adjusting the water content to be 1-10%, and further carbonizing to obtain a carbon template; (2) preparing zirconium sol by taking zirconyl nitrate, zirconium oxychloride, zirconium nitrate and other inorganic zirconium salts as zirconium sources, acetic acid or citric acid as a chelating agent and water and ethanol as solvents; (3) enabling the zirconium sol to permeate the obtained carbon template, after drying, performing heat treatment at a certain temperature to obtain the zirconium carbide wood ceramic. The zirconium carbide wood ceramic prepared by the method has the characteristics of being high in surface area, high mechanical strength, more in pore, strong in thermal shock resistance and low in expansion coefficient, and also has the excellent properties of being favorable in heat insulation, corrosion resistance, abrasion and wear resistance, electromagnetic shielding and the like. Meanwhile, the method is simple in process and the raw materials are low in price and highly available.
