Boron is an important chemical raw material, can be used directly in the processing of borax and boric acid, and then made a series of other borides and elementalboron powder.
Due to the boron powder has the nature of between metal and non-metallic, boron-based substance having physical and chemical properties of the flame retardant, heat resistance, high hardness, high strength, abrasion resistance, catalytic, lightweight and so on, has become an insulating material, glass fiber, ceramic, important part of the detergents, pesticides, flame retardants; Therefore, have the great significance on the development of metallurgy, building materials, mechanical, electrical, chemical, aerospace, medicine, agriculture and other sectors. With the further development of science, scientists from various countries growing interest in this field of research.
Boron-based materials having a high melting point, high hardness, high wear resistance, corrosion resistance, excellent conductivity resistance and the characteristics of the molten metal, and thus is one of the material applied to the surface works. The excellent characteristics make boron-based material (boron carbide, boron nitride, boron transition metal, etc.)becoming one of the primary candidate materials for the application of surface material. The boronizing processing is used for protecting tile production in the steel mold, abrasive dyes (Al2O3, TiO2, B4C) plastic extrusion steel mold.
Numerous studies by metal powder supplier show that sintered, pellets with addition of boron-containing additives can reduce the baking temperature, reduce energy consumption, improve sinter strength and sintering yield, improve quality and metallurgical properties of the pellets. Boron as one of the typical elements with stable chemical structure, can control the generation of dicalcium silicate and prevent its phase transition, thereby inhibiting the sinter reduction in the cooling process, which is the technical problems of iron and steel metallurgy industry must to solve.
Borax, boric acid, phosphoric acid, boron, boric acid, calcium, zinc borate is an important chemical raw materials in the production of ceramics, glazes, glass, flame retardants and other industry. Add these raw materials in the ceramics can enhance the wear resistance and heat-resistant of ceramic, enhance its usefulness; can increase the smoothness of the porcelain surface, making it easier to clean, appreciation is also higher. Adding an appropriate amount of borax, boron oxide, boric acid, boric acid, calcium in the process of manufacturing glass, can reduce the melting temperature of the glass, adjust the viscosity and surface tension of the glass, can make the glass expansion coefficient reduced, to improve its thermal stability and strength, and enhance the gloss and transparency, improve the melting quality. Boron flame retardant has the excellent performance of non-toxic, non-polluting, fire-retardant and smoke suppression, and has been widely used in PVC cable, PE film, epoxy resin, polyimide and various fire-resistant coating such as flame retardant.
Boron and its compounds used in the industry, also widely used in agriculture and other fields. Boron is a trace element necessary for crop growth and development, more and more attention in agricultural production, currently on the market have many varieties of boron-containing fertilizers, commonly used boron fertilizers: borax, boric acid, sodium borate, sodium borate, boron and magnesium fertilizer, boron-containing residue and a wide range of boron foliar fertilizer.
NdFeB permanent magnet materials are widely used as the field of industrial automation, transportation, medical, aerospace, IT booming, especially in high-tech fields, the growing demand for high-performance NdFeB magnets, such as the medical field in the nuclear magnetic resonance imaging equipment, high-speed disk drives in the computer field, the speaker, loudspeakers in the field of communications, CNC machine tools in the field of industrial automation, and power tools, instrumentation and other industries are also widely used NdFeB magnets.

The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
The Evolution and Impact of Abamectin and Emamectin Benzoate in Pest Control
Abamectin and its derivative, emamectin benzoate, have emerged as pivotal substances in the realm of pest control, offering a broad-spectrum efficacy against various pests while maintaining a favorable environmental profile. As the agricultural industry continues to evolve, these compounds have adapted to meet the growing challenges of pest resistance, expanding their market applications and maintaining cost-effectiveness despite rising production costs.
