Silicon carbide graphite crucible is a container applied to hold metal for smelting in a furnace and it can withstand the extreme temperatures encountered in smelting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot.Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and etc.
