Graphite Crucible cup For Casting Gold Silver

1.Materials:

Molded Pressing Graphite 

The moulded graphite is made from the raw materials of high quality pitch, petroleum coke and other aggregate and binding materials, through the processing of grinding, kneading, second grinding, moulded forming, baking, impregnation with pressure, second baking, graphitization in high temperature, refinement etc.

Isostatic Pressing Graphite 

The isotropic graphite is made from the raw materials of high quality pitch, petroleum coke and other aggregate and binding materials, through the processing of grinding, kneading, second grinding, isotropic forming, baking, impregnation with pressure, second baking, graphitization in high temperature, refinement etc. Isotropic graphite is widely used in the fields of semi-conductors, solar & photovoltaic, EDM processing, aerospace & defense, metal continuous casting and other industries. The granule D50 is between 10um to 20um.
