High-thermal-conductivity silicon carbide ceramic and preparation method thereof
According to the silicon carbide ceramic and the preparation method thereof, the granulation process is effectively avoided by adjusting the particle size of silicon carbide powder and the particle size of graphite powder, the powder fluidity is good, dry pressing or/and isostatic pressing can be directly carried out after the powder is mixed with a solvent binder, in addition, the steps after air exhaust vibration and dry pressing and isostatic pressing are combined, and the silicon carbide ceramic is obtained. And the thermal conductivity of the silicon carbide ceramic is greatly improved.
本发明公开了一种碳化硅陶瓷及其制备方法，通过调整碳化硅粉体的粒径和石墨粉体的粒径有效的避免了造粒的工艺，粉体流动性良好，与溶剂粘结剂混合后直接就可以干压或和等静压，此外结合抽气振动并干压等静压后步骤，使碳化硅陶瓷的热导率得到较大提高。
