Pure Tungsten Liner Crucible With Small Sizes Evaporation Coating

Customized Pure Tungsten Liner Crucible With Small Sizes Used in Evaporation Coating

Introduction of Tungsten Crucible:

Like the evaporation tungsten boat, the tungsten crucible is also a typical tungsten product. Tungsten crucible is a high-temperature resistant vessel. The tungsten content is generally higher than 99.95%. Its shape is generally cylindrical, with a diameter of 10mm to 500mm, a height of 10mm to 750mm, and a wall thickness of 8mm to 20mm.

Characteristics of Tungsten Crucible:

The characteristics of tungsten crucible include high specific gravity, high melting point, high boiling point, low vapor pressure, small evaporation rate, low coefficient of thermal expansion, corrosion resistance, wear resistance, good thermal conductivity, etc.

Applications of of Tungsten Crucible:

Tungsten crucible is widely used in rare earth smelting, quartz glass, electronic spraying, crystal growth and other industries. It is mainly used as rare earth metal smelting furnace, quartz glass smelting furnace, induction furnace heater, single crystal furnace high-temperature container, sapphire single crystal growth furnace, high-temperature vacuum furnace and other industrial furnaces. Its working temperature is generally above 2000 ° C. Note: during the growth of sapphire crystal, the tungsten crucible should have the characteristics of no internal crack, accurate size, smooth inner and outer walls, etc.

Condition : Sintering or forging.
