² Products Properties:
—High melting point—2610℃
—High boiling Point—5560℃
—High-density —10.2 g/cm3
—Uniform grain with densified microstructure
—Excellent resistance to electrochemical corrosion
—Low coefficient of thermal expansion
—Good electrical conductivity
² Range of use：
—Molybdenum crucible is widely applied in high temperature vacuum furnace melting environment such as sapphire growing furnace,quartz glass melting furnace,and rare earth melting furnace.The working temperature of tungsten crucible is above 2000℃.
—For sapphire crystal growing furnace,high-purity,high-density,no crack tungsten crucible with other features of exact
measurement and smooth surface has decisive influence on the success of crystal growth,quality control of pulling
crystal,discharging and service life during sapphire growing process.
