Molybdenum Heat Resistant Shields / Vacuum Furnace Molybdenum Heat Shield
Description
As thermal insulation components, molybdenum heat shield and molybdenum covers play a important role for heat blocking and reflecting in sapphire growth furnace. A high purity, precisely sized, smoothly clean, easy assembly and appropriately designed heat shield is significant for crystal pulling quality.
As the heat-shield parts in the sapphire growth furnace, the most decisive function of molybdenum reflection shield is to prevent and reflect the heat in the furnace. Heat-shield parts with high-density, exact-measurement, smooth-surface, convenient-assembly and reasonable-design has great significance in improving the crystal-pulling.

Manufacture process and equipment
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.
