Preparation method of low-density zirconium diboride-silicon carbide foamed ceramic material
The invention discloses a preparation method of a low-density zirconium diboride-silicon carbide foamed ceramic material, and belongs to the technical field of foamed ceramic preparation. In order to solve the problems of difficult forming and sintering shrinkage of the zirconium diboride-silicon carbide foamed ceramic, the preparation method is simple, a silicon carbide template is prepared by dipping a ceramic-containing dipping solution under a vacuum condition, and the zirconium diboride-silicon carbide foamed ceramic is prepared through subsequent drying and sintering steps. Finally, the low-density zirconium diboride-silicon carbide foamed ceramic is obtained. The low-density zirconium diboride-silicon carbide foamed ceramic material prepared by the method has the characteristics of uniform structure, nanoscale crystal grains and excellent mechanical property, and has a good application prospect in the field of high-temperature heat insulation.
