2) Application
As the heating producer of the sapphire crystal growth furnace, W heating module plays a decisive role in the
procedure of AL203 liquor into swift current and producing radial temperature gradient. Hence, the W heating
module with high purity, high density, well made, reasonable design is very important to the quality control,
energy conservation and operational life span of the sapphire crystal.
