  Silicon is a chemical element with the symbol Si and atomic number 14. It is from the same group with carbon, germanium and tin. They all have similar properties, and are all tetravalent metalloid and semiconductor. Silicon powder is made from silicon lump by breaking & milling. Depending on the purity & particle size of the silicon powder, it can be used for many purposes. Semiconductor manufacturing Due to the high melting point, thermal stability, rich resources and higher purity of silicon powder, silicon integrated circuits and large-scale integrated circuits have been applied to various areas. Silicon powder is an important raw materials of electronics and semiconductor industry Coating Industry -High purity Silicon Powder with suitable grain sizes for use in preparation of pressed and bonded sputtering targets and in CVD, PVD processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, ALD, MOCVD.   ...

  Molybdenum is a refractory metal with the symbol Mo and atomic number 42. It is most commonly used as a high temperature, corrosion resistant metal alloy in steel, cast iron and super alloys for the military and defense industry, semiconductor industry and specialty machine shops. Molybdenum metal  products are available in plate, sheet, strip & foil, bar, rod, tube, wire and customized parts. The metal is silvery white, very hard transition metal, but is softer and more ductile than tungsten. It is easier to be rolled in to thinner sheets and have a wider dimension limits than tungsten. It is also easier to machine molybdenum into complex parts than tungsten, that means molybdenum can be made into more precise & smaller parts. Even though, the machining process is similar. Here we will introduce the machining process for molybdenum rod and bar roughly.  After sintering, the molybdenum blank will be forged, to make it with higher density and better mechani...

  Tungsten and molybdenum crucible s perform extremely well in Heat Exchanger Method (HEM) process and are useful for melting and solidifying of single crystals. Formed crucibles from Edgetech have thin walls and exhibit superior creep resistance. Pressed-sintered crucibles are mainly used in the Kyropolous process for the production of sapphire. When sapphire is easily extracted, better yield and improved quality of sapphire can be realized. EDGETECH's tungsten and molybdenum-based crucibles are heat-resistant and feature a smooth surface , which make them durable and cost-effective. They have high density and also resistant to corrosion. Our crucibles are made from tungsten or molybdenum and have a surface roughness of below 0.8-1.6 µm. This feature extends the life of the reusable tungsten crucibles. When the crucible's surface is rough, the sapphire cannot be easily extracted and this tends to damage the crystal. Besides, the crucible might get damaged in the process...
