Sapphire Tungsten Crucible Process

Tungsten is a metal crucible tungsten products, mainly divided into sintering

tungsten crucible

(applied to the powder metallurgy technique), metal forming, spinning type.Turning the use of tungsten rod shape (usually relatively small size), forming a variety of welding, using pure tungsten plate, tungsten sheet and pure tungsten rod through the appropriate processing technology. Tungsten crucible at 2600 degrees below the inert gas used in a vacuum.

Melting point of tungsten high boiling point, high temperature strength, wear resistance, corrosion, thermal conductivity, thermal expansion coefficient, good hardenability. Tungsten crucible smelting of rare earth is widely used, quartz glass, electronic spraying, crystal growth,etc.

Tungsten melting point, boiling point, high temperature strength, anti-friction, corrosion resistance, thermal conductivity, thermal expansion coefficient, good hardenability, thanks to such excellent properties, tungsten is widely used in rare earth smelting crucible, quartz glass, e-coat , crystal growth and other industries.

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.
