无论是高致密均匀制品还是多孔材料制备，无论是制件还是粉末，对于钨粉的粒度及粒度均匀性要求非常苛刻且各有差异，因此分散分级操作是粉末制备过程中不可缺少的重要环节。本数据集为，采用液体分散剂，进行湿法机械打散，操作时间30min。该方法可以实现部分粉末粒度范围宽化。钨粉在进行分散操作时，部分硬团聚在机械作用下消失，但是由于范德华力影响，细粒径粉末又重新形成软团聚。

Whether it is a high-density uniform product or a porous material preparation, whether it is a product or a powder, the particle size and particle size uniformity of tungsten powder are very strict and different. Therefore, the dispersion and classification operation is an indispensable and important link in the powder preparation process. In this data set, liquid dispersant is used for wet mechanical dispersal, and the operation time is 30 minutes. This method can achieve a widening of the particle size range of some powders. During the dispersion operation of tungsten powder, part of the hard agglomeration disappeared under mechanical action, but due to the influence of van der Waals force, the fine particle size powder re-formed soft agglomeration.
