Quartz Continuous Melting Furnace

Application:

Quartz glass is silicon dioxide constituent of glass whose hardness can reach Morse seven levels. It has a series of excellent physical and chemical properties: high temperature resistance, low expansion coefficient, heat shock resistance, chemical stability and good electrical insulation, and ultraviolet and infrared lights can pass through.

As a result of the quartz’s high melting point 1750℃, when we want to melt the quartz, we need the container with higher melting point. So the refractory metal molybdenum is widely used in quartz melting industry.

Material Properties:

Tungsten has the characters of high melting point, high strength at elevated temperature, low electrical resistivity, lower thermal expansion, low work function of electron emission and low vapor pressure.
