Fabricated Pure Tungsten Crucible in High Temperature as Melting Pot

Description of Tungsten Crucible:

Tungsten crucible, also known as tungsten melting pot, can be mainly divided into such molding ways as sintering molding (powder metallurgy technology is applied thereto), impact molding, spinning molding, lathing molding (usually has relatively small size) and using tungsten rod and welding processing with the appropriate technology.

Owing to the feature of tungsten that its melting point reaches 3410℃, tungsten crucible is widely applied in the industry of furnace such as sapphire growth furnace, quartz glass melting furnace, single crystal furnace, induction furnace and rare earth smelting furnace. And the temperature of tungsten crucible in working environment is above 2000℃. In the event of sapphire crystal growth furnace, high-purity, high-density, no internal-crack tungsten crucible with other features of exact measurement and smooth surface have a decisive effect on the success ratio of seed growth, quality control of pulling crystal, metamictization pot-committed and service life during sapphire growth process.

Advantages of Sanhui Tungsten Crucible:

1. Our tungsten crucible has excellent high temperature heat resistance, electrical conductivity, creep resistance, corrosion resistance

2.Lower vapor pressure

3. Tungsten material of high purity can prevent the contamination to evaporation material and substrate

Application of of Tungsten Crucible:

1. Tungsten crucibles can be applied in sapphire growth furnace, quartz glass melting furnace, single crystal furnace, induction furnace, etc.

2. They also play a significant role in machinery processing, glass and ceramic manufacturing, metallurgical industry and light industry.

3. Tungsten crucible liners are very useful in electron-beam evaporation as they typically increase the evaporation rates of the material deposited. They also facilitate the task of changing evaporation materials. And we can provide crucible liners in a variety of sizes

Condition : Sintering or forging.
