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.
