Product Description

Tungsten Crucible

Since the melting point of tungsten has reached 3410ºC, Tungsten crucible is widely applied in industry furnace such as sapphire growth furnace. Quartz glass melting furnace and rare earth smelting furnace. The temperature in working environment of tungsten cruible is above 2000ºC, for sapphire crystal growth furnace, high-purity. High-density, no internet  crack tungsten crucible with other features of exact measurement and smooth inner surface has decisive influence on success ratio of seed growth quality control of pulling crystal metamictization pot-committed and service life during sapphire growth process.

Physical and chemical properties

  • Purity : W99.95%
  • Density : 18.2g/cm3.
  • Application temperature environment : 2400ºC
Features
  • It has more than 99.95% purity level
  • Its density is more than 18.2 g/cm3.
  • It requires around 2300ƒ working temperature
  • Categorized as per its mold type
Advantages
We offer an entire set of testing apparatus with this item to determine its surface roughness condition, density, hardness, fracture and porosity level in order to ensure its standard quality.
  • The offered item is used as an essential part of quartz glass melting furnace, induction furnace, single crystal furnace and sapphire growth furnace.
  • It is also utilized as an important element of ceramic production and glass manufacturing works. Its application can also be noticed in light manufacturing and metallurgy industries.
  • The offered item helps to improve evaporation level of electron beam. We offer it in different sizes.
