Preparation method for silicon carbide ceramic material
The invention discloses a preparation method for a silicon carbide ceramic material. The preparation method comprises: grinding bamboo charcoal to powder by using a ball mill; adding silicon powder and phenolic resin to be uniformly mixed, wherein the molar ratio of bamboo charcoal and silicon powder is 1: (1-1.1) and the ratio of mass of the mixture of the silicon powder and bamboo charcoal and the volume of the phenolic resin is 1: (1-1.1); pre-heating the mixture at 140-150 DEG C to form; and then raising the temperature to 1600-1700 DEG C in a vacuum or argon atmosphere for high-temperature sintering for 30-35 minutes to obtain the silicon carbide ceramic material. The silicon carbide ceramic material prepared by the preparation method disclosed by the invention has good adsorption property, resistivity and corrosion resistant rate and can be used for preparing a conductive material, an adsorption material, a corrosion-resistant material, an antioxidant material and a high-temperature-resistant material.
