W/Mo heat shielding has good heat insulation effect, could block and reflect effect on heat.
Tungsten shields has good corrosion resistance. At normal temperature, it is not easy to react adversely with chemical substances such as inorganic acids and alkaline.
Molybdenum shilding has excellent high temperature resistance. Its volume is relatively stable and not easy to change with changes in temperature.
Tungsten shield has strong antioxidant capacity. Compared with other heat shields, tungsten heat shields have stronger oxidation resistance, but these shields working in vacuum or inert atmosphere environments is better.
Used in vacuum resistance furnaces, it can effectively insulate the heat in the furnace from being transferred to the outside of the furnace.
Used in sapphire single crystal furnaces to prevent heat loss and ensure uniform temperature in the hot zone.
Furnace hot zone parts are our professional advantaged products. We could design the furance hot zone for you.
At first we will make sure that we got all customer's requirements clear. Then place order to production department and inspection department. Each production process will test themselves if everything is right.
