SPECIFICATION

Medium-grain Graphite

Medium grain graphite materials are ideally suited for large parts or components used for graphite furnace, polycrystalline silicon furnace, casting mold and crucibles.

Unlike high purity graphite and isostatic graphite materials, medium grain graphite materials don’t need to be meshed together with other pieces.

Consequently, it will be easier to install and more cost efficient due to a low consumption and leakage risk.
