Payment Method: L/C, T/T Silicon carbide Silicon carbide (SIC) is smelted with quartz sand, petroleum coke or (coal), sawdust as raw materials by high temperature resistance furnace. There are SiC existing in rare mineral, Moissanite. Silicon carbide is also called Moissanite. In contemporary era, C, N, B etc. non oxide refractory high-tech materials, silicon carbide is the most widely and economically used. TYPES Silicon carbide has two commonly used basic varieties, black silicon carbide and green silicon carbide, which are all belonging to α-SiC. Black silicon carbide contains SiC about 98.5%, its toughness is higher than green silicon carbide. Most of the material is used for processing low tensile strength of materials, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals. Green silicon carbide contains SiC 99% above, good self-sharpening, mostly used for processing hard alloy, titanium alloy and optical glass, and can also be used to hone the cylinder and fine grinding HSS Cutting Tools. In addition, there is cubic silicon carbide, is specially processed yellow green crystals. grinding tools produced by it is suitable for ultra precision machining of bearing.

Sand blasting 1.Surface- polishing treatment of stainless steel products of steel, steel pipe, steel structure, surface polishing treatment, sand blasting treatment before spraying. 2. Cleaning of various molds； 3. Cleaning to remove burrs before tin of semiconductor device, plastic tube 4. Shot peening for strengthening light of medical equipment, textile machinery and all kinds of hardware products 5. Cleaning and removal of burr residue of all kinds of metal pipes, non-ferrous metal precision castings 6. Grinding and polishing,etc. Photovoltaic products such as Monocrystalline silicon, polysilicon and piezoelectric crystal of the electronics industry. Raw material for manufacturing silicon tetrachloride ; main raw material of silicon resin industry Processing materials in engineering—for line cutting of 3 - 12 inches Monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal. Processing materials in engineering such as solar photovoltaic industry, semiconductor industry, piezoelectric crystal of engineering work materials. Deoxidizer of steel and iron; modifier of cast iron structure --A new type of strong composite deoxidizer, which shortens the time of deoxidizing, saves energy, increases the efficiency and reduces the consumption of raw materials, decreases environmental pollution, improves work conditions and enhances the comprehensive economic benefits of electric furnace; Refractory material-- silicon carbide has high resistance to corrosion, high temperature resistance, high strength, good thermal conductivity, impact resistance and other characteristics.It is made of high-grade refractory materials with thermal shock resistance, small volume, light and high strength, good energy saving , which can be used for all kinds of smelting furnace lining, high temperature furnace kiln component, silicon carbide plate, lining board, strutting piece, saggar, silicon carbide crucible. Ceramic material – Making high-grade silicon carbide ceramic materials for making wear resistance, corrosion resistance, high temperature resistance, etc. Silicon carbide ceramics has good chemical corrosion resistance, high strength, high hardness, good wear resistance, low friction coefficient, and high temperature resistance, which is the ideal material for sealing ring NOTICES: Transport and loading: In the transport process, silicon carbide can’t be dragged by iron hook, should prevent to be mixed with the solid material, strong vibration, friction, trample, smashing. Throwing strictly forbidden. And it should be lightly loaded and unloaded, to reduce the breakage of packing. Storage: it should be stored in cool and dry place, preventing inner and outside package from break, damp,other materials and contamination source. Strictly forbid water: carborundum belong to advanced abrasive, so during the process of transport, storage and use, we need to forbid water absolutely, or it will influence the application result. |
