Silicon carbide composite ceramic and preparation method thereof
According to the silicon carbide multiphase ceramic material and the preparation method thereof, silicon carbide powder with specific parameters (particle size, angular coefficient and stacking density) is used as a raw material, and the operations of air exhaust and low-frequency vibration on laid powder in the 3D printing process are combined, so that a high-density silicon carbide ceramic material biscuit is obtained; the density of the prepared silicon carbide ceramic material biscuit can reach 1.90 g/cm < 3 >. The silicon carbide multiphase ceramic material with the same biscuit density is prepared, the number of times of subsequent densification treatment is reduced, the process is simplified, and energy is saved.
本发明公开了一种碳化硅复相陶瓷材料及其制备方法，本发明通过以具有特定参数(粒径、角形系数、堆积密度)的碳化硅粉体为原料，结合3D打印过程中的对铺层粉体进行抽气并低频震动的操作，实现了高密度的碳化硅陶瓷材料素坯，所制备得到的碳化硅陶瓷材料素坯的密度可达1.90g/cm3。制备同样素坯密度的碳化硅复相陶瓷材料，降低了后续的增密处理的次数，简化了工艺，节约能源。
