Preparation method of compact MoAlB ceramic material, product of compact MoAlB ceramic material and preparation method of high-purity MoAlB ceramic powder
The invention discloses a preparation method of a compact MoAlB ceramic material, a product of the compact MoAlB ceramic material and a preparation method of high-purity MoAlB ceramic powder. The preparation method of the compact MoAlB ceramic material comprises the following steps: S1, burdening molybdenum boride powder, aluminum powder and molybdenum powder serving as raw materials; s2, carryingout dry mixing on the ingredients on a ball mill for 1-4 hours to obtain a mixture; s3, putting the mixture into a graphite mold, putting the graphite mold into a plasma sintering furnace for prepressing, and sintering in a protective atmosphere according to the parameter conditions that the heating rate is 50-200 DEG C/min, the sintering temperature is 800-1200 DEG C, the pressure is 50-100 MPaand the heat preservation and pressure maintaining time is 5-30 minutes; and S4, after heat preservation and pressure maintaining, cooling to room temperature to obtain the compact MoAlB ceramic material. According to the scheme, synthesis can be realized at a relatively low sintering temperature, the heating and cooling speed is high, the process period is effectively shortened, the energy consumption is reduced, and the efficiency is improved; meanwhile, the amount of impurities is greatly reduced, and the purity of a final product is improved.
本发明揭示了致密MoAlB陶瓷材料的制备方法、其产物及高纯度MoAlB陶瓷粉的制备方法，致密MoAlB陶瓷材料的制备方法包括如下步骤：S1,以硼化钼粉、铝粉和钼粉为原料进行配料；S2,将配料在球磨机上干混1～4小时得到混合料；S3，将混合料置于石墨模具中，将石墨模具放置于等离子烧结炉中进行预压，在保护气氛下，按照升温速率在50～200C/min之间，烧结温度在800C～1200C之间，压力在50～100MPa之间，保温保压时间在5～30分钟之间的参数条件进行烧结；S4，保温保压后，降温至室温，得到致密MoAlB陶瓷材料。本方案能够在相对低的烧结温度下实现合成，且加热冷却速度块，有效的缩短工艺周期，降低了能耗，提高了效率；同时极大的减少了杂质的量，改善了最终产品的纯度。
