Crystal Growth Furnace with Tungsten Crucible

Sapphire crystal growth furnace thermal field and supporting tungsten and

molybdenum crucible with a high density, high purity, high precision machining.

tungsten crucible

Tungsten crucible is one of tungsten products, mainly divided into sintered molding, stamping, spinning type, the use of molybdenum rod turning forming, welding molding variety, using pure tungsten plate, tungsten plate and pure tungsten rod through the appropriate processing technology from. 2600 degrees in a vacuum with an inert gas.

The melting point of tungsten, high boiling point, high strength, anti-friction, corrosion resistance, thermal conductivity, thermal expansion coefficient, good hardenability, widely used in rare earth smelting, quartz glass, electronic coating, sapphire crystal growth and other industries.

Sapphire crystal growth as the main carrier, tungsten crucible temperature, low thermal expansion coefficient of the sapphire growth to meet the conditions at high temperatures, the tungsten material of the crucible is not easy to react with the alumina, sapphire ensure purity.
