The invention provides tantalum carbide slurry and a preparation method thereof, a tantalum carbide coating and a tantalum carbide product. The preparation method comprises the following steps: mixing tantalum carbide powder and a binder to obtain first slurry; sequentially carrying out spray drying treatment, first screening, pre-sintering treatment and second screening on the first slurry to obtain spherical tantalum carbide particles; the particle size of the spherical tantalum carbide particles is 10 [mu] m-30 [mu] m; mixing the spherical tantalum carbide particles with the tantalum carbide powder, a sintering aid, a nonionic polymer binder and an organic solvent to obtain a mixture; the particle size of the tantalum carbide powder ranges from 0.05 micrometer to 0.5 micrometer. And carrying out wet ball milling on the mixture to obtain the tantalum carbide slurry. The tantalum carbide slurry prepared by the method provided by the invention can reduce pores or cracks of a tantalum carbide coating and improve the relative density of the coating.
本申请提供了一种碳化钽浆料及其制备方法、碳化钽涂层和碳化钽制品。所述制备方法包括如下步骤：将碳化钽粉末和粘结剂混合，得到第一浆料；对所述第一浆料依次进行喷雾干燥处理、第一次过筛、预烧结处理和第二次过筛，得到球形碳化钽颗粒；所述球形碳化钽颗粒的粒径为10μm~30μm；将所述球形碳化钽颗粒与所述碳化钽粉末、烧结助剂、非离子型聚合物粘结剂和有机溶剂混合，得到混合物；所述碳化钽粉末的粒径为0.05μm~0.5μm；对所述混合物进行湿法球磨，得到碳化钽浆料。采用本申请的方法制备得到的碳化钽浆料能够减少碳化钽涂层的孔隙或开裂、并提高涂层的相对密度。
