High purity and density Sintering and Forging sapphire crystal tungsten crucible
Tungsten crucible with good high temperature oxidation resistance and electrochemical corrosion resistance, under the operating conditions of high temperature deformation, is a good auxiliary material. And because molybdenum and molybdenum alloy crucible has characteristic of low pollution, it is widely used for the sapphire crystal growing furnace, rare earthsmelting container, heater in induction furnace, quartz glassmelting furnace
Advantages: high melting point, good performance under high temperature, high hardness, low electrical resistivity, low expansion coefficient, low electron work function
