Customized Machining Pure Tungsten Melting Pot Applied in Evaporation Coating
Description of Tungsten Melting Pot:
Tungsten melting pot, also known as tungsten crucible, can be mainly divided into sintering molding (powder metallurgy technology is applied thereto), impact molding, spinning molding, lathing molding (usually has relatively small size) according to molding ways 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.
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

Advantages:
We are able to supply a complete set of testing equipment for physical properties like density, hardness, surface roughness and so on. Accordingly, the possible internal injury of tungsten crucible like porosity and crack can be strictly inspected while using the eddy current tester and ultrasonic equipment, so as to ensure the high quality.
