Due to the melting point of molybdenum is as high as 2610℃, so the molybdenum crucible is widely used in sapphire crystal growth furnace, quartz glass melting furnace, rare earth smelting furnace etc core container of the industrial furnace, its working temperature environment generally above 2000℃.
Vessels of molybdenum have also been used for such applications as processing nuclear fuel pellets at temperatures up to 1650 C (3000 F), and molybdenum crucibles are durable and will withstand repeated rough handling. In air or oxygen-containing atmospheres, molybdenum is not oxidized to any considerable degree at temperatures below 400 C (750 F).
Molybdenum Crucible. We can provide two kinds of molybdenum crucibles. One is sintering product, its density is among ~ 10g/cc; the other one is forging product, its density can reach /cc. Molybdenum crucible is mainly used in metallurgy industry and mechanism process industry, and it??????s a kind of indispensability material in rare
Molybdenum has extremely good resistance to corrosion by numerous acids, liquid metals and molten glass, provided oxidizing agents are not present. Molybdenum is relatively inert in hydrogen, ammonia, and nitrogen up to about 1100°C. TAG: Molybdenum-Crucible
Molybdenum and Tungsten Crucibles Elmet produces molybdenum and tungsten material and components for leading sapphire growth furnace OEMs and crystal growers around the world. Elmet provides a variety of crucibles for sapphire growth furnaces, as well as many other components for these furnaces.
During sapphire production, Al 2 O 3 - the compound that is to become the future single crystal - is melted in molybdenum and tungsten crucibles. It is in the Kyropoulos process that our pressed-sintered crucibles show their strengths to best effect. They are repeatedly heated to more than 2000°C (3632 °F) and then cooled down again.
Tool steels contain elements such as chromium, molybdenum, tungsten, and vanadium. These elements combine with the excess carbon to form chromium carbides, tungsten carbides, vanadium carbides, etc. These carbide particles are microscopic in size, and constitute from less than 5% to over 20% of the total volume of the microstructure of the steel.
Molybdenum crucible is sintered or forged from the ultimate material—molybdenum powder. Generally speaking, molybdenum crucible is used pure molybdenum, for its purity can prevent melting metal powder from mingling. The density of molybdenum crucible is more than g/cm3, and its working temperature is among 1100℃.
Molybdenum is a lustrous, silvery coloured metal which has an abundance of ppm in the earths crust. In many instances, it shows a resemblance to tungsten with which it tends to be paired in the transition series in the periodic table, but their chemistries tend to show more distinct differences than might be expected.
Metal left to solidify in a crucible can expand on re-heating and destroy it. Please temper new crucibles or those that have been in storage. Heat the empty crucible for 2 hours at 220 F (104 C). (Use adequate ventilation. New crucibles will smoke as the glaze sets.) Then fire the empty crucible to a red heat. Allow the crucible to cool to room temperature in the furnace before use.
Specialist applications often require specialist crucibles. At high temperatures following materials: Molybdenum; Nickel; Inconel? 601; Tantalum; Zirconium
Molybdenum is a refractory metal recognized for its excellent strength at high temperatures, its high melting point of 2610 C (4370 F) and its high resistance to
