Preparation method of tantalum carbide powder
The invention discloses a preparation method of tantalum carbide powder, and belongs to the technical field of structural ceramics. Comprising the following steps: S1, mixing glucose monohydrate, tantalum pentoxide and water, heating and stirring in a water bath, and then adding an organic monomer, a cross-linking agent and a catalyst to obtain mixed gel; s2, carrying out segmented heat preservation treatment on the mixed gel obtained in the step S1: carrying out heat preservation at 80 DEG C for 24 hours, carrying out heat preservation at 100 DEG C for 24 hours, carrying out heat preservation at 120 DEG C for 12 hours, carrying out heat preservation at 146 DEG C for 4 hours, carrying out heat preservation at 180 DEG C for 4 hours and carrying out heat preservation And S3, putting the mixed gel treated in the step S2 into a crucible, carrying out segmented high-temperature treatment, and carrying out furnace cooling to obtain the tantalum carbide powder. The prepared TaC ceramic powder is small in grain size, uniform in particle size distribution and high in purity, and the preparation method is easy to operate, high in efficiency, environmentally friendly and safe.
本发明公开了一种碳化钽粉体制备方法，属于结构陶瓷技术领域。包括以下步骤：S1、将一水合葡萄糖、五氧化二钽与水混合，水浴加热搅拌，再加入有机单体、交联剂和催化剂，得到混合凝胶；S2、对步骤S1得到的所述混合凝胶进行分段保温处理：80℃保温24h，100℃保温24h，120℃保温12h，146℃保温4h，180℃保温4h，200℃保温4h；S3、将步骤S2处理后的所述混合凝胶放入坩埚中进行分段高温处理，随炉冷却后，得到碳化钽粉体。本发明制备的TaC陶瓷粉体晶粒尺寸小、粒径分布均匀、纯度高，制备方法操作简单、效率高、环保安全。
