Preparation method of titanium diboride ultrafine powder
The invention relates to a preparation method of titanium diboride ultrafine powder, which comprises the following steps: putting composite molten salt into a vacuum drying oven, and drying to remove moisture, so as to obtain a first substance; mixing titanium dioxide and boron powder to obtain a second substance; mixing the first substance and the second substance, manually grinding to uniformly mix the first substance and the second substance, and putting the mixture into a corundum crucible; putting the corundum crucible into a tubular furnace for calcining, heating under the protection of an argon atmosphere, keeping the temperature for a period of time, and then cooling to obtain a third substance; the third substance cooled to the room temperature is taken out and dissolved in deionized water, residual salt and by-products are removed, and a fourth substance is obtained; and filtering the fourth substance, repeatedly washing the fourth substance with deionized water and absolute ethyl alcohol, and drying the filtered product to obtain the required product. The production process is simple and environment-friendly, and no high-risk substances are generated and remained in the production process and after production; the raw materials of the product are relatively low in price, and the product performance is good.
本发明涉及一种二硼化钛超细粉体的制备方法，步骤如下：将复合熔融盐放入真空干燥箱干燥以去除水分，获得第一物质；将二氧化钛和硼粉进行混合，获得第二物质；将第一和第二物质进行混合，手动研磨使两者混合均匀并放入刚玉坩埚内；将刚玉坩埚放入管式炉中煅烧，在氩气氛围的保护下升温并保温持续一段时间，然后进行冷却，获得第三物质；将冷却到室温后的第三物质取出并在去离子水中溶解，去除残余的盐和副产物，获得第四物质；将第四物质进行过滤，并用去离子水和无水乙醇反复清洗，并将过滤所得产物烘干，获得所需产品。本发明的生产工艺简单，环境友好，生产过程和产后无高危物质的生成和残留；本发明的产品原料价格相对低廉，产物性能好。
