B-SIC Cubic Silicon Carbide Powder Introduction and Application

Cubic silicon carbideBeta SiC, is a synthetic high-performance material (only a small amount of high-purity cubic silicon carbide exists in nature). It is called "cube" because its structure belongs to the cubic system (diamond crystal). This structure also determines its own superior physical and chemical properties. B-SiC has a Mohs hardness range of 9.5 to 9.75, which is close to the most Mohs hardness diamond in the natural world (10 Mohs hardness) and is one of the hardest high performance materials after diamond.

B-SiC has excellent chemical stability, high thermal conductivity, high hardness, low thermal expansion coefficient, wide band gap, high electron drift speed, high electron mobility, special resistance temperature, etc. It has anti-wear, high temperature resistance and resistance. Excellent performance such as thermal shock, corrosion resistance, radiation resistance and strong semi-conductivity. Therefore, B-SiC can be widely used in optical instrument manufacturing, electronic component production, ultra-precision grinding, high-precision machining of metal products, advanced refractory production, structural ceramic material preparation, advanced SiC product preparation, and coating and coating of military materials and many other fields.
Our company uses the infinite micro-heat source technology independently invented to produce Beta SIC, which is produced using self-developed special raw materials. We can offer 50nm, 100nm, 1-3um, 5um, 10um, please feel free to ask us a quote.

The main application areas of B-SiC are as follows:

1 Metal grinding and polishing industry
Ultra-precision grinding tools based on B-SiC have begun to be widely used in machinery manufacturing, material processing and other fields. Its material properties are far stronger than traditional materials such as green silicon carbide, alumina (corundum), zirconia, and boron carbide. In addition, B-SiC made a variety of abrasives can greatly extend the service life of abrasives under the premise of maintaining high level of grinding, which can help manufacturers significantly reduce the number of abrasives replacement, reduce labor intensity and improve Productivity. At present, the abrasive abrasives of B-SiC base materials have achieved excellent market feedback in the grinding and polishing related industries, and have been unanimously recognized by all adopting enterprises.

2 slurry market
B-SiC slurry is mainly used in the field of terminal grinding in the form of liquid plus abrasive. It is mainly used for grinding and polishing of silicon wafers, glass, stainless steel and other products. This type of product is mainly used to replace diamond micropowder. In the processing of products with Mohs hardness below 9, B-SiC slurry and diamond slurry can achieve the same processing effect, but the price of B-SiC powder is only a fraction of that of diamond powder.
3 Fine grinding and polishing market
Compared with other abrasives of the same particle size, B-SiC has the highest processing efficiency and cost performance. In the replacement of diamond and other abrasives for processing copper, aluminum, tungsten iron, stainless steel, cast iron, solar panels, silicon wafers, gemstones, jade, electronic and electrical products, B-SiC has a better cost performance.

4 Fine chemical raw materials for advanced ceramics and refractory products
B-SiC can be used as raw material or additive for pressureless sintered ceramics, reactive sintered ceramics, recrystallized ceramics and hot-pressed sintered ceramics. It produces all kinds of beams, rollers, slabs, seals, wear-resistant and corrosion-resistant parts and knives. , α-SiC, such as quenching ducts, squirting nozzles, sand blasting nozzles, heat pipes, sputum, sputum, temperature measuring tubes, thermocouple protection tubes, bulletproof armor, body armor, armor and even shaped structural parts. The irreplaceable advantage of micronized powder. Its pressureless sintered product density can easily reach 3.15g/m3.

5 mechanical seal
B-SiC is a high performance sealing surface material. It can be applied in the fields of automobiles, locomotives, ships, military equipment, aviation and aerospace, ensuring reliable and durable non-leakage during the life of the equipment. Related product density can generally reach 3.1~3.16g/cm3.

6 Defence military
All kinds of armor, bulletproof panels and body armor made of β-SiC micro powder and new whisker materials have excellent hardness, pressure resistance and elastic modulus. Its products have excellent ballistic barrier capabilities to withstand high kinetic energy strikes such as warhead shrapnel. Tank bearings, engine burners, etc. can also use B-SiC properties to improve mechanical properties. B-SiC can also be used as a high-performance radar antenna material and infrared fairing material for military equipment such as fighters, bombers, aircraft carriers, and submarines. As an excellent absorbing material, β-SiC micropowder and whisker also have great potential for the application of stealth fighter body coating materials in China (the absorbing coatings of US B-2, F-117 and other stealth bombers use high purity). β-SiC is used as a raw material).
7 Aerospace
B-SiC micropowders and whiskers have excellent corrosion resistance, high thermal conductivity and ultra-high strength, making them possess physical properties unmatched by other materials. They can be used in spacecraft burner batteries, combustion systems, valves, high temperature power auxiliary components. , cover, skeleton, insulation system and so on.

8 Chemical Environmental Protection
In the field of chemical environmental protection, β-SiC can be widely used in various nozzles, actuators, igniters, radiant tubes, burners, co-current heaters, gasoline reforming crackers, refractories, valves, filters, scrubbers. , wastewater treatment systems and other aspects.

9 Electronics Industry
B-SiC micropowder products are attractive for high temperature, high frequency, high power semiconductor devices, UV detectors, short wavelength LEDs, high temperature and radiation resistant digital integrated circuits due to their excellent electrical and thermal properties. Raw materials. As a high-grade raw material for SiC single crystal and SiC target materials, it has broad application prospects. As an electronic packaging material, B-SiC has also been favored by many high-tech workers.

What is silicon carbide whiskers and its application

Silicon carbide whiskers are a kind of single-crystal fiber with a certain length-to-diameter ratio, which has very good high temperature resistance and high strength. It is mainly used in toughening applications where high temperature and high strength applications are required. Such as: aerospace materials, high-speed cutting tools. At present, it has a very high performance-price ratio. Silicon carbide whiskers are cubic whiskers, and diamonds belong to a crystal form. They are the whiskers with the highest hardness, the largest modulus, the highest tensile strength and the highest heat resistance temperature. It is both α-type and β-type, in which β-type performance is better than α-type and has higher hardness (Mohs hardness of 9.5 or more), better toughness and electrical conductivity, anti-wear, high temperature resistance, especially earthquake resistance Corrosion-resistant, radiation-resistant, has been applied to aircraft, missile casings and engines, high-temperature turbi...

Acetamiprid is one of the safety Insecticide for agriculture

Insecticide acetamiprid  is an organic compound with the chemical formula C10H11ClN4. It is an odorless neonicotinoid insecticide produced under the trade names Assail, and Chipco by Aventis CropSciences. It is systemic and intended to control sucking insects (Lepidoptera, Thysanoptera, Hemiptera, mainly aphids) on crops such as leafy vegetables, citrus fruits, pome fruits, grapes, cotton, cole crops, and ornamental plants.
