The invention relates to a tantalum carbide feed, a tantalum carbide product and a preparation method thereof. The tantalum carbide feed comprises the following components in parts by mass: 90-95 parts of tantalum carbide composite powder and 5-10 parts of a wax-based binder, and the tantalum carbide composite powder comprises tantalum carbide powder and a sintering aid. According to the tantalum carbide feed, the wax-based binder with good surface affinity with the tantalum carbide is selected to replace an organic solvent, the mass fraction of the tantalum carbide in the feed is as high as 90-95 wt%, and a tantalum carbide coating with high density and few cracks can be prepared by adopting the tantalum carbide feed; the obtained tantalum carbide product can meet the performance requirement of high-purity ceramic single crystal growth on a substrate material.
本申请涉及一种碳化钽喂料、碳化钽制品及其制备方法。所述碳化钽喂料按质量份记，包括以下组成：90份~95份碳化钽复合粉末、5份~10份蜡基粘结剂，所述碳化钽复合粉末包括碳化钽粉末和烧结助剂。上述碳化钽喂料选用与碳化钽具有良好表面亲和性的蜡基粘结剂取代有机溶剂，喂料中碳化钽的质量分数高达90wt%~95wt%，采用该碳化钽喂料可以制得致密度较高、裂痕较少的碳化钽涂层，所得碳化钽制品能够满足高纯陶瓷单晶生长对衬底材料的性能需求。
