High-density SiBCN ceramic material and preparation method thereof
The invention discloses a high-density SiBCN ceramic material and a preparation method thereof, relates to a SiBCN ceramic material and a preparation method thereof, and aims to solve the problems oflow density, small size and low production efficiency of the SiBCN ceramic material prepared by the existing mechanical alloying-hot pressing sintering method. The high-density SiBCN ceramic materialis prepared from cubic silicon powder, graphite powder and hexagonal boron nitride powder. The method comprises the following steps: weighing silicon powder, graphite powder and hexagonal boron nitride powder of a cubic crystal system, putting into a ball milling tank for ball milling, then carrying out hot-pressing presintering, and finally sealing into a sheath for hot isostatic pressing, thereby completing the preparation of the high-density SiBCN ceramic material. The preparation method is used for preparing the high-density SiBCN ceramic material.
