² Products Properties:

  High melting point2610℃                          

  —High boiling Point5560℃                    

  —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.
