Molybdenum tube is a tubular material made of pure molybdenum or molybdenum alloy after processing
Molybdenum circle has the characteristics of good electrical and thermal conductivity, high strength, small thermal expansion coefficient and good processing performance. It is an indispensable substrate material for the production of silicon rectifier complete sets of equipment and semiconductor silicon devices. The chemical composition of the molybdenum wafer is stable, the molybdenum content is as high as 99.9%, the size is accurate, the surface roughness is low, and the surface roughness can reach below Ra≤ 1.6μm.
Molybdenum crucible is a high-purity molybdenum material made of high-temperature resistant, corrosion-resistant container. Molybdenum is a chemical element with a melting point as high as 2623°C, so molybdenum crucibles can maintain stability at extremely high temperatures and are used for high-temperature experiments or processes. Molybdenum crucibles have excellent physical and chemical properties, such as high melting point, good thermal conductivity, creep resistance and chemical stability, which make them perform well under high temperature, high pressure and strong corrosive environment.
Molybdenum bolt is a kind of semiconductor device material, which is made of high temperature molybdenum rod and has stable physical properties at 1700 ℃. The product types are M2 (screw outer diameter is 2mm)~ M32 (screw outer diameter is 32mm)* L (length), and can make hexagonal head molybdenum bolts, countersunk head molybdenum bolts, square head molybdenum bolts, slotted molybdenum bolts, T-shaped molybdenum bolts, special-shaped molybdenum bolts and other specifications. It is widely used to fix high temperature resistant mechanical parts, sintering furnace fasteners, etc. In terms of civil use, molybdenum screws are widely used in vacuum furnaces, single crystal furnaces, LED furnaces, glass ceramics and other equipment.
Molybdenum foil is one of the molybdenum products. It is through the powder metallurgy of molybdenum plate, after mechanical processing of 0.2mm flat rolling molybdenum, that is, molybdenum foil, its minimum purity of 99.9%. The processing of molybdenum foil is mainly to obtain the corresponding mechanical properties. The main processing processes include bending, spinning, drawing, stamping, etc., so that it can be used under high temperature and low temperature conditions. It is roughly the same as the nature of the molybdenum plate. Xiamen China Tungsten Online Technology Co., Ltd. can produce molybdenum foils of different shapes and types according to the thickness, surface conditions and tolerances required by customers. Molybdenum foil is widely used in electronics, electrical components, tensile products, furnace insulation and corrosion-resistant products.
Molybdenum block is one of the common molybdenum products, and its surface presents silver-white metallic luster or gray-black powder (body-centered cubic crystal). Melting point 2623 ℃. Boiling point 4800 ℃. Relative density 10.2. Soluble in hot concentrated nitric acid, hot concentrated sulfuric acid, aqua regia, slightly soluble in hydrochloric acid, insoluble in water, hydrofluoric acid and liquid ammonia. It has good corrosion resistance, can resist the erosion of high temperature, oxidation and corrosive environment, and is widely used in electronic and optoelectronic industries. In addition, molybdenum blocks are often made into high-temperature structural parts for different high-temperature fields.
