Tungsten crucibles are high-temperature containers known for their exceptional heat resistance and corrosion resistance, even in the presence of strong acids and alkalis at high temperatures. Because of these properties, tungsten crucibles are invaluable for high-temperature reactions and melting processes. They are widely used in industries such as rare earth metallurgy, quartz glass production, electron beam coating, and crystal growth.
There are several methods for manufacturing tungsten crucibles, including sintering (using powder metallurgy), stamping, spinning, machining from tungsten rods (typically for smaller sizes), and welding. The choice of manufacturing method depends on the specific industry and application. If you have any questions or requirements, feel free to contact us for more information.
