Tungsten crucibles are vessels or containers made primarily from tungsten metal. They are widely used in high-temperature applications, particularly in industries such as metallurgy, semiconductor manufacturing, and research laboratories. Tungsten crucibles are typically made from pure tungsten or tungsten alloys.Tungsten (W) has a high melting point, anti-friction/corrosion resistance and small thermal expansion coefficient.widely used for growing mono-crystals, electronics. Crucibles are available in round, square, rectangular, conical, etc.
