Features & Applications of Tungsten Crucibles

Tungsten crucible, as its name implies, is one of the products made of metal tungsten, which is widely used in today’s industrial production. But do you know what are the features & applications of tungsten crucibles? What process is used to manufacture tungsten crucibles? What are the advantages of tungsten crucibles? If not, keep reading and in this article, we’ll try to answer the above questions.

Features & Applications of Tungsten Crucibles

What processes are used to manufacture tungsten crucibles?

The tungsten crucibles currently on the market are mainly made by three processes: sintering, stamping, and spinning. Different processes will make tungsten crucibles have different ranges of use. Tungsten crucibles are generally made of pure tungsten plates, tungsten sheets, and pure tungsten rods processed by corresponding processes.

Because tungsten has a relatively high melting point and boiling point, good strength, abrasion resistance, corrosion resistance, high thermal conductivity, and a small thermal expansion coefficient, you must be extra cautious in the process of manufacturing tungsten crucibles to avoid unnecessary losses.

What are the features and applications of tungsten crucibles?

Because the melting point of tungsten is as high as 3410°C, tungsten crucibles are widely used as core vessels in industrial furnaces such as sapphire single crystal growth furnaces, quartz glass melting furnaces, rare earth smelting furnaces, etc. Its working temperature is generally above 2000°C.

Especially for the sapphire single crystal growth furnace, the tungsten crucible featuring high purity, high density, no internal cracks, precise dimensions, smooth inner and outer walls, etc. plays a key role in the success rate of seeding, the quality control of crystal pulling, the sticking of crystals, and the service life in the sapphire crystal growth process.

What are the advantages of tungsten crucibles?

In practical applications, tungsten crucibles have attracted more and more attention because of their high melting point, good high-temperature strength, High thermal conductivity, good hardenability, abrasion resistance, corrosion resistance, and low thermal expansion coefficient.
