Then they load the crucible into a furnace for 24hours and allows it to gradually heat the disc ring to temperature of 3000 o F until the silicon is melted completely. This liquid silicon is then drawn into the disc ring by the pores of the framework of the disc ring and forms a completely new material called silicon carbide which makes the disc ring exceptionally hard.
