High-purity compact WAlB MAB phase ceramic block material and preparation method thereof
The invention provides a preparation method of a high-purity compact WAlBMAB-phase ceramic block material. The preparation method comprises the following steps: step 1, burdening by taking tungsten boride powder and aluminum powder as raw materials or boron powder, tungsten powder and aluminum powder as raw materials; step 2, adding a ball milling medium into the raw materials, and carrying out wet mixing at a preset rotating speed for preset time to obtain a mixture; step 3, drying the mixture at a preset temperature for a certain time to obtain a dried mixture; step 4, pre-pressing the dry mixture, then heating and pressurizing according to a preset heating rate and a preset pressurizing rate in a vacuum environment or a protective atmosphere, and sintering for preset sintering time after a preset sintering temperature and preset pressure are reached, so as to obtain a sintered block; and step 5, cooling the sintered block to room temperature according to a preset cooling rate to obtain the high-purity compact WAlB ceramic block material. The invention also provides a high-purity compact WAlBMAB phase ceramic block material which is prepared by using the preparation method disclosed by the invention.
本发明提供了一种高纯度的致密WAlBMAB相陶瓷块体材料制备方法，包括以下步骤：步骤1，以硼化钨粉末、铝粉为原料或以硼粉、钨粉、铝粉为原料进行配料；步骤2，向原配料加入球磨介质，以预定转速和预定时间进行湿混得到混合料；步骤3，将混合料在预定温度和一定时间下干燥，得到干燥混合料；步骤4，将干燥混合料进行预压，随后在真空环境或保护气氛下，按照预定升温速率和预定加压速率进行升温和加压，达到预定烧结温度和预定压力后，在预定烧结时间下进行烧结，得到烧结块；步骤5，将烧结块按照预定降温速率降温至室温后，得到高纯度的致密WAlB陶瓷块体材料。本发明还提供了一种高纯度的致密WAlBMAB相陶瓷块体材料，为利用本发明中的制备方法制得。
