Ⅳ,Application
As the heat shield parts in the sapphire growth furnace, molybdenum heat shield, molybdenum upper cover and bottom cover have the key influence on the heat reflection.
High purity, accurate dimenisons, smooth surface, easy assembly, and reasonable design of the molybenum heat insulator will be very important for the sapphire ingot quality.
