Graphite Crucible A crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength

2015813The crucible 1 for growing a sapphire single crystal in which the coating layer 5 was formed by the thermal spraying method was produced and used to melt sapphire, followed by cooling, and then an attempt was made to take sapphire out of the crucible. A specific process is as described below.
Tungsten crucible is widely used to the sapphire growth furnaces, quartz glass melting furnace, crystal furnace, induction furnace, sintering metal mold of high melting point, electronic beam coating, and rare earth smelting furnace.
It is an important part of the high-temperature furnace because of its high melting point. Tungsten crucible and other pure tungsten & molybdenum parts can be used for sapphire crystal growth and rare-earth melting due to their high temperature resistance, low pollution and other excellent characteristics.
Tungsten crucible is widely used in sapphire single crystal growth furnace, quartz glass melting furnace, rare earth smelting furnace and other core containers of industrial furnace. Its operating temperature environment is more than 2000 degrees. Tungsten crucible is widely applied in vacuum sintering, laser crystal growth and other industries.
Our production line of tungsten and molybdenum products includes powder, rod, wire, plate, sheet, and alloy as well as fabricated parts. The main products include all kinds of tungsten electrodes for TIG welding, hot zones parts in sapphire growth furnace,etc.
Molybdenum crucible is mainly used in metallurgy industry and mechanism process industry, and it s a kind of indispensability material in rare earth smelting industry. Molybdenum crucibles are more frequently used in crystalloid materials, and other burgeoning high technology industry.
Tungsten crucible for thermal sources in vacuum evaporation Tungsten crucible is a commonly used evaporation source due to its high purity, high melting point and low vapor pressure. Many factors that determine the evaporation performance are largely associated with the quality of crucible containing the evaporation materials.
The melting point of the vacuum coating crucible is 2610ºC and the density is higher than the sintered crucibles. Molybdenum crucibles are widely used in sapphire single crystal growth and the industry of silex glass, melting furnace and rare-earth smelting.
20181219These products could be widely used in different fields, such as rare earth, glass fiber, aluminum silicate fiber, industrial stoves, glass cotton, optical glass. Industrial ceramics. Vacuum furnace, electric light source etc. Products of high quality export to Europe. America, southeast, Asia and other 30 more countries.
This crucible for use in growing a sapphire single crystal has a cylindrical inner vessel which consists either of molybdenum and unavoidable impurities or of a tungsten-molybdenum alloy having a tungsten content of 0.1 to 60 mass% and unavoidable impurities and which has a bottom that has a thickness of 0.3 to 2mm and that is integrally formed
Tungsten Crucibles - Product & Service - ATTL Advanced Materials 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
Molybdenum Crucibles. Due to the advantages of high density, high temperature resistance, low pollution and other good characteristics, molybdenum crucible is widely used for sapphire crystal growth, rare-earth melting, mechanism process, metallurgy and LED Evaporation Boats and Coils of Molybdenum
Uses a metal mold made up of two sections - used for low melting point metals - refractory material molds are made for higher temp metals Steps: - mold is preheated and coated for lubrication and heat dissipation. - cores (if needed) are inserted and molds is closed. - molten metal is poured in - mold is opened
20181211Calcium oxide is also alkaline special refractories. Although it has a high melting point, it is easy to hydrate and produce pulverization, which is greatly restricted in application. The products of calcium oxide can be used as special refractories for melting platinum, ultrapure uranium and nonferrous metals crucible and jet metallurgy.
201319Sapphire manufacturers can benefit from this product as it eliminates complex and costly processes. In addition, the smooth surface is resistant to corrosion induced by the aggressive melted sapphire. This feature extends the life of the reusable tungsten crucibles. PLANSEE's molybdenum crucibles are in huge demand.
Because molybdenum melting point 2610 ℃, molybdenum crucible is widely used in sapphire crystal growth furnace, quartz glass melting furnace, industrial furnace, such as rare earth smelting furnace is the core of the container, its use working temperature environment generally above 2000 ℃.
