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 turbine rotors, special components.

Silicon carbide is an extremely anisotropically grown crystal. It is a short fiber crystal grown on the basis of a silicon carbide particle by a catalyst. The current production methods mainly include a gas phase reaction method and a solid material method, among which the solid material method is more For the economy, it is more suitable for industrial production.

In addition, it acts as a reinforcing component to join the plastic matrix, metal matrix or ceramic matrix to enhance and toughen, and utilizes the high thermal conductivity, high insulation of nano Sic materials, and substrates for large-scale integrated circuits in the electronics industry. Packaging material. As an information optical material, it has high application value in the fields of television display, modern communication, and network.

Silicon carbide whiskers are used in the manufacture of high-strength plastics, metals and ceramics to accelerate the upgrading of key traditional products. Due to the excellent function of nano-silicon carbide whiskers, it has a special role in the aerospace industry, namely in the application of aircraft and missile casings, as well as the application of engines, high-temperature turbine rotors, special components, so it is in the military industry and There is a huge demand in the civilian industry.

Our company SAT NANO can supply best quality beta SiC silicon carbide whisker powder, please feel free to ask us a quotation.

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. It is also a key pesticide in commercial cherry farming due to its effectiveness against the larvae of the cherry fruit fly. Insecticide acetamiprid  is an insecticide belonging to the chloropyridinyl neonicotinoids, this family of insecticides was introduced in the early 1990s. This compound is an insecticide that is introduced for controlling pests, but also for domestic use to control fleas on cats and dogs. Mechanism of action: Insecticide acetamiprid  is a nicotine-like substance and reacts to the body in a similar way as nicotine. Nicotine is a n...

Sodium Cyclamate

Sodium cyclamate is no harm to human and has sugar-free and low-calorie food-grade sweetener although 30-50 times sweeter than sucrose .Sodium cyclamate is physically stable, resistent to heart acid and alkaline. Food additives sweeteners Sodium Cyclamate wholesale Sodium cyclamate is a white needle, flake or crystalline powder, an active pharmaceutical ingredient product that is stable under heat, does not absorb moisture in the air, does not ferment, and food grade cyclamate should be stored in a cool, dry, well ventilated place. He is a non-nutritive synthetic sweetener with a sweetness of 30-50 times that of sucrose and a price of only one-third of sucrose. It is widely used as a food additive in the world for refreshing beverages, fruit juices, ice cream, pastry foods and preserves. - Taste sweet,no bitter feeling - Harmless to health - Physically stable,resistent to heat,acid and alkaline - Easy of storage,do not absorb water from air,does not ferment Application: Sodium cyclama...

Hydroxyapatite - the new century bone

Due to the influence of diseases, aging, frequent traffic accidents and other factors, the number of cases of bone injury has increased year by year. According to statistics, there are 3 million orthopedic cases every year in China, and the demand for bone substitute materials is increasing. In recent years, bone substitute materials represented by hydroxyapatite have gradually become the darling of clinical application. Hydroxyapatite  is a major component of vertebrate bones and teeth and has good biological activity and biocompatibility. Compared with traditional metal (stainless steel, titanium alloy) and ceramic (alumina, silicon nitride) bone substitute materials, hydroxyapatite is not only highly resistant to corrosion and osteoinductive, but also its degradation in vivo is eliminated. The security risks of the former. At present, the research on hydroxyapatite in bone substitute materials mainly focuses on two aspects, hydroxyapatite coating and human bone bionic regenerati...
