Isostatic graphite means that the raw material mixture is compressed into rectangular or round blocks. In addition, isostatic graphite generally tends to have the smallest grain sizes of all artificial graphites. In this process, crucible void content is low and density is large, homogeneous and erosion resistance is strong.

The milling and mixing effect is realized through intensive movement and the impacts of grinding media (usually ceramic balls, short cylinders, or rods). In a ball mill the grinding bodies tumble in a rotating cylindrical powder container. In an attrition mill the grinding bodies are agitated by stirring arms mounted on an axial shaft.

He et al. firstly showed the relationship between the morphology of GNPs and ball milling time using a planetary ball mill with Al 2 O 3 powder. The rotation speed steadied at 250 r·min −1 with a powder-to-ball ratio of 1:30. With the milling time increasing, the majority of the graphite sheets were broken, some exfoliations of GNPs occurred ...

Hot Isostatic Pressing. HIP is used as a post-sintering operation to eliminate flaws and microporosity in cemented carbides. It is predicted that as HIP vessels increase in size the economics of the process will be sufficiently attractive to allow its use even on low-alloy steel structural PM parts in order to achieve full-density.
