Factory Supply Metallurgy Siliziumkarbid Silicon Carbide¹

Product Description Carborundum, also known as silicon carbide (SiC), is produced by smelting raw materials such as quartz sand, petroleum coke (or coal coke), and wood chips (salt needs to be added when producing green silicon carbide) in a resistance furnace at high temperatures. Silicon carbide also exists as a rare mineral in nature, moissanite. Silicon carbide is also known as carborundum. Among the contemporary non-oxide high-tech refractory materials such as C, N, and B, silicon carbide is the most widely used and economical one, and can be called emery or refractory sand. At present, silicon carbide produced in China's industrial sector is divided into two types: black silicon carbide and green silicon carbide. Both are hexagonal crystals with a specific gravity of 3.20 to 3.25 and a microhardness of 2840 to 3320kg/mm 2. Silicon carbide has two commonly used basic varieties: black silicon carbide and green silicon carbide, both of which belong to α-SiC. Black silicon carbide contains about 95% SiC and has higher toughness than green silicon carbide. It is mostly used for processing materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals, etc. Green silicon carbide contains over 97% SiC and has good self-sharpening properties. It is mostly used for processing hard alloys, titanium alloys and optical glass, and is also used for honing cylinder liners and fine grinding of high-speed steel tools. In addition, there is cubic silicon carbide, which is a yellowish-green crystal produced by a special process. The grinding tools made from it are suitable for the ultra-precision processing of bearings, and can process the surface roughness from Ra32 to 0.16 microns to Ra0.04 to 0.02 microns in one go. Specification Black Silicon Carbide ItemSiCFe2O3Free CarbonSiO2SiC97≥97%≤1.0%≤0.5%≤1.5%SiC95≥95%≤1.5%≤1%≤2.5%SiC92≥92%≤2.0%≤2.5%≤3.5%SiC90≥90%≤2.5%≤3%≤4.0%Green Silicon Carbide SiC99≥99%≤0.2%≤0.2%- Application Silicon carbide has a wide range of applications, mainly including the following aspects:1. Abrasives and grinding tools: Silicon carbide has excellent wear resistance and is widely used in the preparation of grinding tool products.2. Refractory materials: Silicon carbide can be used to make refractory bricks, silicon carbide crucibles, silicon carbide furnace charges and other products, playing an important role in the production of the steel industry.3. Coatings industry: Silicon carbide has excellent wear resistance and corrosion resistance. When added to Teflon non-stick (PTFE) coatings, UV coatings, and fluorocarbon coatings, it can significantly enhance the oxidation resistance and corrosion resistance of the coatings. It is widely used in outdoor architectural coatings, power plant coatings, and ship coatings.4. Electronic devices: Silicon carbide has excellent thermal conductivity and high-temperature stability, and is often used to prepare electronic heat sinks, electronic packaging materials, power semiconductor devices, etc.5. Ceramic products: Silicon carbide can be used to prepare various ceramic products, such as ceramic seals, ceramic bearings, ceramic pipes, silicon carbide nozzles, etc.6. Chemical industry: Due to its excellent corrosion resistance and high-temperature stability, silicon carbide can be used to manufacture chemical equipment and pipelines, such as reactors, storage tanks, and pipelines. The application of silicon carbide in the chemical industry can enhance the corrosion resistance and high-temperature resistance of equipment and extend its service life.7. Automotive industry: Silicon carbide has excellent friction and wear resistance as well as high-temperature stability, and can be used to manufacture automotive parts, such as engine components, brake pads, clutch plates, etc. The application of silicon carbide in automotive manufacturing can enhance the wear resistance and high-temperature resistance of components, improving the performance and reliability of automobiles.8. Optoelectronic industry: Due to the excellent optical properties of silicon carbide, such as high transparency and low refractive index, it can be used to manufacture optical equipment and optical components, such as optical fiber connectors, optical devices, solar cells, etc. Silicon carbide can also be used to prepare high-purity monocrystalline silicon, which is applied in fields such as optoelectronics, semiconductors and optical communications.9. Abrasives and grinding tools industry: Due to its high hardness and wear resistance, silicon carbide can be used to manufacture abrasives and grinding tools, such as sandpaper, grinding wheels, and abrasive discs. Silicon carbide abrasives have excellent grinding performance and wear resistance, and can be used in fields such as metal processing, glass processing, and ceramic processing.10. Metallurgical industry: Silicon carbide is mainly used as a deoxidizer and purifying agent in the metallurgical industry. It can remove oxygen and other impurities from steel and improve the quality of steel. In addition, silicon carbide can also be used as a lining material for furnaces to protect the furnace body from high-temperature erosion.11. Jewelry industry: The application of silicon carbide in the jewelry industry is mainly reflected in its potential as a substitute for diamonds. Because silicon carbide is structurally similar to diamond, it can be used to make high-quality jewelry. It is more lustrous, cheaper, more durable and lighter than diamond. These characteristics make it a valuable alternative to diamonds in the jewelry industry.12.LED: Silicon carbide is used to manufacture blue, red and yellow leds. LED is used in televisions, display boards and computers.13. Fuel: Besides being used in the above-mentioned fields, silicon carbide can also be used as fuel. In steel manufacturing, silicon carbide is used as fuel and can produce purer steel than most other fuels. In addition, it is also a cheaper and more environmentally friendly fuel option.14. Military field: Silicon carbide can be used to manufacture bulletproof armor. Bullets and other harmful objects will have to contend with the hard ceramic blocks formed by silicon carbide. Bullets cannot penetrate ceramic blocks. Shengjinyao(Shanxi)New Material Co.,LTD was established in 2025 and is located in Shanxi,China.We are mainly engaged in the business of Washing material,plastic pellets,food ingredients,and additives.After more than ten years of industry development and learning,we have established long-term partnerships with domestic and foreign partners.With the concept of quality first,integrity management,and mutual benefit,we have been supporting our partners and customers to develop many new products and new markets,establishing a very important relationship of trust for both parties.We closely follow the "One Belt,One Road"policy,constantly develop new markets and new products,and contribute to China's export industry.We have a professional and experienced team focusing on marketing,procurement,logistics,insurance and after-sales service,with warehouses inChina's main ports:Qingdao,Shanghai and Tianjin,with the above safeguards,we have established for our partners Safe,robust and professional international services.
