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.
一种高致密SiBCN陶瓷材料及其制备方法,本发明涉及SiBCN陶瓷材料及其制备方法。本发明要解决现有机械合金化‑热压烧结法制备SiBCN陶瓷材料的密度低,尺寸小,生产效率低的问题。一种高致密SiBCN陶瓷材料由立方晶系的硅粉、石墨粉和六方氮化硼粉制备而成。方法:称取立方晶系的硅粉、石墨粉和六方氮化硼粉,并放入球磨罐中球磨,然后热压预烧结,最后封入包套进行热等静压,即完成高致密SiBCN陶瓷材料的制备。本发明用于高致密SiBCN陶瓷材料及其制备。
