High Quality Tungsten Crucibles

We are indigenous manufacturer and exporter of a superior range of Tungsten Crucibles in Zhuzhou, Hunan, China. 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 3410a , 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 2000a . 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.
