Molybdenum Heat Shield

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.
