Preparation method of high-purity titanium diboride ceramic powder
The invention discloses a preparation method of high-purity titanium diboride ceramic powder, and belongs to the technical field of preparation of novel ceramic materials. The preparation method is characterized by comprising the following steps: 1) uniformly mixing titanium dioxide, a boron source and a reducing agent according to a mass ratio of 8: (6-9): (11-15) to obtain a mixed raw material; the reducing agent is a composition of one or two of calcium powder and magnesium powder in any proportion; (2) the mixed raw materials are loaded into a self-propagating reaction furnace, a self-propagating reaction is initiated under argon protection, a titanium diboride crude product is obtained, and the reaction temperature is controlled to range from 400 DEG C to 700 DEG C; and (3) the titanium diboride crude product is subjected to acid leaching, washing and drying, and titanium diboride powder is obtained. The method is short in technological process and low in production cost, and the prepared titanium diboride ceramic powder is high in purity, narrow in particle size distribution, high in activity and easy to sinter.
一种高纯二硼化钛陶瓷粉末的制备方法，属于新型陶瓷材料制备技术领域。其特征在于，制备步骤为：1)将二氧化钛、硼源与还原剂按照8：6～9：11～15的质量比混合均匀，得到混合原料；所述的还原剂为钙粉、镁粉中的一种或两种的任意比例组合物；2)将混合原料装入自蔓延反应炉，在氩气保护下，引发自蔓延反应得到二硼化钛粗产物，反应温度控制在400℃～700℃；3)将二硼化钛粗产物进行酸浸、洗涤、干燥，得到二硼化钛粉体。该方法工艺流程短、生产成本低，制备的二硼化钛陶瓷粉末纯度高、粒径分布窄、活性高、易于烧结。
