3、 Application
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.
