Application of Tungsten and Molybdenum Products in Glass Melting Furnaces

Photovoltaic Industry

Tungsten (W) and molybdenum (Mo) possess high melting points, high strength, excellent thermal conductivity, and low thermal expansion coefficients. These properties make them highly stable under high-temperature, high-vacuum, and corrosive environments, which has led to their wide application in the photovoltaic industry.

Sapphire Growth Furnace

Sapphire single crystals are typically grown using the Kyropoulos (KY), Czochralski (CZ), or Heat Exchange Method (HEM). These processes require extremely high temperatures between 1800–2100°C to melt high-purity alumina and allow it to crystallize slowly. Therefore, all high-temperature structural materials used in the furnace must exhibit excellent heat resistance, chemical stability, and thermal conductivity.

Semiconductor Industry

Tungsten (W) and molybdenum (Mo) products play an important role in the semiconductor industry, mainly due to their high melting points, high thermal conductivity, low thermal expansion coefficients, and excellent chemical stability. The detailed applications are as follows:

Vacuum Coating Industry

Tungsten (W) and Molybdenum (Mo) are widely used in key components of the vacuum coating industry due to their excellent high-temperature performance, good thermal conductivity, and corrosion resistance. Vacuum coating is commonly applied in optical films, decorative coatings, functional films, and semiconductor devices.

Vacuum Furnace

Tungsten, molybdenum, and their alloys possess high melting points, excellent strength, good thermal stability, and outstanding creep resistance. These characteristics make them ideal structural and heating materials for use in vacuum, high-temperature, and inert gas environments. In the vacuum furnace industry, tungsten and molybdenum products are widely used in various types of vacuum heat treatment furnaces, vacuum brazing furnaces, and vacuum sintering furnaces due to their superior physical and chemical properties.
