Preparation method of tantalum oxide particles
The invention relates to the technical field of optical evaporation materials, in particular to a preparation method of tantalum oxide particles. Comprising the following steps: S1, drying tantalum oxide and tantalum powder for later use; s2, grinding tantalum oxide, filtering feed liquid, and drying an obtained filter cake to obtain a mixture; s3, uniformly mixing the mixture with tantalum powder, pressing the mixture into blocks, and then crushing and screening the blocks to obtain mixed particles; s4, the mixed particles are put into a roller stirring tank to be stirred, and pretreated mixed particles are obtained; and S5, carrying out vacuum sintering on the pretreated mixed particles, then cooling to room temperature, and then sequentially carrying out screening, vacuum packaging and warehousing, thereby obtaining the product. The tantalum powder and the tantalum oxide are ground, so that the granulated ceramic particles are more compact, and the mechanical property of the sintered material is better; the specific surface area of the raw material is increased, the surface energy is increased, abnormal growth of grains can be effectively prevented, the activity of the raw material is increased, the sintering temperature is reduced, and the sintering time is shortened.
本发明涉及光学蒸镀材料技术领域，更具体的，涉及一种氧化钽颗粒物的制备方法。包括以下步骤：S1，将氧化钽、钽粉经干燥处理备用；S2，将氧化钽进行研磨，过滤料液，得到的滤饼进行烘干，得到混合物；S3，将混合物与钽粉混合均匀，压制成块状，然后粉碎筛分，得到混合颗粒物；S4，将混合颗粒物放在滚筒搅拌罐中进行搅拌处理，得到预处理混合颗粒物；S5，将预处理混合颗粒物进行真空烧结，然后冷却至室温，再依次进行筛分、真空包装以及入库，即得。将钽粉、氧化钽进行研磨，造粒后的陶瓷颗粒更致密，烧结后材料的力学性能更好；原材料的比表面积增加、表面能增高，可有效防止晶粒异常生长，同时原料的活性增加，烧结温度降低，烧结时间变短。
