Condition of molybdenum foil :Vacuum Anneal and un-annealed
Tungsten and molybdenum materials are widely used in industry because of their high temperature resistance, corrosion resistance and low pollution. So molybdenum foil can be used as hot zone and parts in sapphire crystal growth furnace and high temperature furnace.
As the heat-shield parts in the sapphire growth furnace, the most decisive function of upper and bottom cover plate is to prevent and reflect the heat in the furnace. Molybdenum foil as heat-shield parts with high-density, exact-measurement, smooth-surface, convenient-assembly and reasonable-design has great significance in improving the crystal-pulling.
Advantage of our W/Mo reflection shield
2. uniform grain with densified microstructure ensures longer service time
3. precise machining tolerance.
In order to achieve the best application performance of the furnace, some thermal field components will also use molybdenum lanthanum alloy, TZM alloy, tungsten molybdenum alloy, tungsten lanthanum alloy and other materials.
