Composite ceramic material and preparation method thereof
The invention belongs to the technical field of high-tech materials, and particularly relates to a composite ceramic material and a preparation method thereof. Boron carbide powder, silicon carbide powder, titanium carbide powder, amorphous carbon powder, phenolic resin, polyetherimide and polyvinyl butyral are used as raw materials. The preparation method comprises the following steps: carrying out secondary ball milling on slurry, granulating powder, putting the granulated powder into a mold, carrying out dry pressing molding to obtain a green body, putting the green body into a pressurelesssintering furnace, carrying out pressureless high-temperature sintering under the condition of vacuum or argon protection, naturally cooling, and cooling to room temperature to obtain the composite ceramic material product. The method has the following advantages: the sintering temperature is reduced, various properties of the composite material are improved, meanwhile, the sintering difficulty is reduced, and the method has great practical significance.
本发明属于高新材料技术领域,具体涉及一种复合陶瓷材料及其制备方法。以碳化硼粉、碳化硅粉、碳化钛粉、无定形碳粉、酚醛树脂、聚醚酰亚胺、聚乙烯醇缩丁醛为原料；经过二次球磨浆料、造粒粉，对造粒粉放入模具内进行干压成型，得到生坯，将生坯放进无压烧结炉内，在真空或氩气保护的条件下进行无压高温烧结后自然冷却，冷却到室温后得到复合陶瓷材料制品。本发明具有降低烧结温度，对复合材料的各项性能进行了提升，同时降低了烧结难度，十分具有现实意义。
