Sintered Tungsten Crucible
Sintered tungsten crucible is a high-purity refractory metal container manufactured through powder metallurgy. It is primarily utilized in ultra-high temperature vacuum environments, such as sapphire crystal growth furnaces, monocrystalline silicon thermal fields, electron beam evaporation, vacuum coating systems, and high-temperature metal smelting equipment, etc.
Sintered tungsten crucible, fabricated from high-purity tungsten powder, undergoes Cold Isostatic Pressing (CIP), molding, and high-temperature vacuum sintering. This process densifies the material, enhancing structural uniformity, high-temperature strength, and creep resistance, ensuring excellent dimensional stability and structural integrity under prolonged high-temperature conditions.
Key features of CTIA's sintered tungsten crucible:
(1) High Melting Point: About 3422°C, suitable for extreme environments exceeding 2000°C.
(2) Low Volatility: Extremely low high-temperature vapor pressure minimizes contamination and impurity introduction in high-vacuum systems.
(3) High Purity: ≥99.95%, with zero carbon contamination, ideal for high-purity material preparation.
(4) Creep Resistance: Superior resistance to high-temperature deformation and structural collapse during prolonged operation.
(5) Thermal Stability: Withstands repeated heating and cooling cycles while maintaining structural integrity.
(6) Reliability: Offers longer service life and higher structural reliability compared to traditional ceramic containers.
(7) Shape Flexibility: Available in cylindrical, tapered, and customized shapes.
(8) Customization: Supports customized dimensions, wall thicknesses, and geometries to match specific thermal field and vacuum equipment requirements.
CTIA GROUP, with over 30 years of manufacturing expertise, delivers comprehensive, end-to-end customized solutions for high-purity, high-density, and thermally stable sintered tungsten crucibles.
