Extruded graphite is mainly in round shape, and also with small quantity of square shape.
Main applications are as following:
1. Used to machine graphite crucibles, boats/dish, molds, rotor and shaft, launder, graphite densener and so on.
2. Used as structural material in high temperature furnace.
3. Used as blank materials for machined graphite parts in environment of strong acid, strong alkali and strong erosion. Such as industries of rare earth, chemicals and so on.
4. Used to machine graphite electrodes.
