pure tungsten crucible 99.96% /Polished seamless pure tungsten alloy crucible

A tungsten crucible is a container made of tungsten, a hard and dense metal with a high melting point. Tungsten is known for its excellent thermal conductivity, low thermal expansion, and high strength, making it an ideal material for use in high-temperature applications.

Tungsten crucibles are commonly used in the production of materials that require high-temperature melting and casting, such as metals, glasses, and ceramics. They are also used in the production of semiconductor materials, such as silicon, germanium, and gallium arsenide.

Tungsten crucibles are highly resistant to corrosion and chemical attack, making them ideal for use in harsh environments. They are also highly durable and can withstand repeated use at high temperatures without cracking or breaking.

The production of tungsten crucibles typically involves the process of powder metallurgy, where tungsten powder is mixed with a binding agent and compressed into the desired shape. The resulting compact is then sintered at high temperatures to form a dense and uniform material.

Overall, tungsten crucibles are a valuable material that is used in a variety of applications due to its unique properties and characteristics, including its high melting point, excellent thermal conductivity, low thermal expansion, and high strength.
