Molybdenum Heat Shield: 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.
