Tungsten Crucible
Tungsten Crucible
Tungsten crucibles are containers made of pure tungsten metal or tungsten alloys used for high-temperature applications such as melting and casting metals, sintering ceramics, and crystal growth. Tungsten has a high melting point of 3422°C, which makes it an ideal material for high-temperature applications.
Tungsten crucibles are usually made by powder metallurgy techniques, such as sintering tungsten powder or forging tungsten rods, and they can withstand high temperatures without melting, deforming or reacting with other materials. They are also resistant to thermal shock and corrosion, making them suitable for use in harsh environments.
Tungsten crucibles are commonly used in the semiconductor, aerospace, and nuclear industries, as well as in research laboratories. They come in different shapes and sizes, such as cylindrical or conical, and are often used in conjunction with other tungsten components, such as heating elements or filaments.
