Tungsten crucible is made of tungsten powder and mainly used for high quartz continuous melting furnace in the vacuum or inert gas under 2600℃. we can provide regular density 18.3 g/cm3 (or less) and high density crucible (18.5
The hot zones in sapphire growing furnaces use molybdenum and tungsten products for furnace components and fixtures. These high temperature materials are characterized by their high thermal and electrical conductivity, low coefficient of thermal expansion, and excellent strength and stability at temperatures above 2,000°C.
Tungsten crucible is widely used in technologies for growing monocrystals from molten corundum, itis also used in electronics and technologies for thermal vaporization - deposition of various substances. It is an important part in high temperature furnace cause its high melting point.
Arc Melt Furnace ABJ-900 is our small bell jar furnace and reaches 3500C instantly. The melt area is 9" in diameter. Hinged chamber for loading.
Crucibles must never be heated above their maximum temperature. This can lead to dangerous crucible failure. However, operating below the crucible's lower temperature limit can also cause problems. For example, crucibles designed for the high temperature melting of copper-based alloys will oxidize if used at low temperatures for zinc melting.
Introduction to tungsten crucible Tungsten crucibles are vessels made of tungsten or tungsten alloys and are used for melting and calcining materials at high temperatures. Tungsten crucibles are increasingly being used for a variety of purposes and are being produced by many companies.
Nov 27, 2019 · A melting crucible is usually a pot-shaped container placed in the center of a furnace that is used to hold a metal to be melted. It is commonly made of silicon carbide and graphite, but can also be composed of metals suited to high temperature applications, such as tantalum or tungsten.
Tungsten Crucible: A crucible is a container that can withstand very high temperatures and is used for metal, glass, and pigment production as well as a number of modern laboratory processes. In past centuries crucibles were usually made from clay, they can be made from any material that withstands temperatures high enough to melt or otherwise alter its contents.
Tungsten smelting crucible for sapphire growing furnace, Tungsten crucible is widely applying in high temperature vacuum furnace melting environment such as LED sapphire growing furnace 1. Physical and chemical properties (1) Density: 18.0~19.2g /cm3 (2) Surface roughness: < 3.2 (3) Purity: W99.95%(min) (4) Application temperature environment: 1800~2600C

The process for melting tungsten is called induction skull melting. Basically several hollow fingers of copper are used to form the crucible in which the tungsten is melted. The hollow copper fingers are liquid cooled with water to keep the copper from melting at the extremely high melting temperatures needed to melt the W.
There are 247 metal melting furnace tungsten crucible suppliers, mainly located in Asia. The top supplying country is China, which supply of metal melting furnace tungsten crucible respectively. Metal melting furnace tungsten crucible products are most popular in North America, South America, and Oceania.
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℃.
Formed molybdenum and tungsten crucibles excel in the so-called HEM process (Heat Exchanger Method). They are the perfect vessels for melting and solidifying the single crystal. Our formed crucibles have particularly thin walls combined with excellent creep resistance.
Tungsten crucible is widely used in technologies for growing monocrystals from molten corundum, it is also used in electronics and technologies for thermal vaporization – deposition of various substances. It is an important part in high temperature furnace cause its high melting point.
Copper crucible and other parts can be used for sapphire crystal growth and rare-earth melting due to their high temperature resistance, low pollution and other excellent characteristics. Stanford Materials supplies all kinds of copper crucibles used in the process of sapphire growth and rare-earth melting and we can manufacture the products
