What is boron nitride powder? Boron nitride is a ceramic material with excellent thermal conductivity. The boron nitride ceramic powder produced by Yinuo Materials has high purity, uniform particle size distribution and chemical stability. The oxidation resistance temperature of boron nitride in an oxygen atmosphere can reach 900 ℃It also has good lubricity at high temperatures. It is an excellent high-temperature solid lubricant. At the same time, it is chemically inert to almost all molten metals. It can withstand high temperatures up to 2000 ℃. Its molded products have better performance for machining.
Advantages of boron nitride powder Boron nitride products are made of high-quality boron nitride, which has the characteristics of high-temperature resistance, non-adhesion, corrosion resistance, heat dissipation, and heat conduction. It is not wet with aluminum water and can provide comprehensive protection for the surface of materials directly in contact with molten aluminum, magnesium, zinc alloys, and their molten slag. 1. The product is hard and can be made into high-speed cutting tools and drill bits for geological exploration and oil drilling 2. Different shapes can be used as high-temperature, high-voltage, insulation, and heat-dissipation components 3. Packaging materials that can be used to prevent neutron radiation 4. Special electrolytic and resistance materials that can be used at high temperature
Basic structure of boron nitride powder 1. High heat resistance: sublimated at 3000 ℃, its strength at 1800 '℃ is twice that of room temperature, it does not crack when cooled to room temperature by air at 1500' ℃ for dozens of times, and it does not soften at 2800 ℃ in inert gas 2. High thermal conductivity: hot-pressed products are 33W/m, k is the same as pure iron, which is the material with high thermal conductivity in ceramic materials above 530 ℃ 33. Low thermal expansion coefficient: 2 * 10-6 is second only to quartz glass, which is small and medium in ceramic. In addition, it has high thermal conductivity, so it has good thermal shock resistance 4. Excellent electrical properties: good insulation at high temperatures, 1014Q-cm at 25 ℃, and 103 Ω - cm at 2000 c ℃. It is a good high-temperature insulation material in ceramics, with a breakdown voltage of 3KV/mm, low dielectric loss, 2-5 * 10-4 at 108Hz, the dielectric constant of 4, and microwave and infrared transmission 5. Good corrosion resistance: it does not react with general metals (iron, copper, aluminum, lead, etc.), rare earth metals, precious metals, semiconductor materials (germanium, silicon, potassium arsenide), glass, molten salts (crystal stone, fluoride, slag), inorganic acids, and alkalis 6. Low friction coefficient: μ It is 0.16, which does not increase at high temperatures. It is higher than molybdenum disulfide. The temperature resistance of graphite is higher. The oxidation atmosphere can be up to 900 ℃, and it can be up to 2000 ℃ under a vacuum 7. High purity and high content of B: its impurity content is less than 10PPM, while the content of B is more than 43.6%.
Price of boron nitride powder Boron nitride powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of boron nitride powder. A large amount of large amount will be lower. The price of boron nitride powder can be found on our company's official website.
