HBN boron nitride powder ( cas no 10043-11-5 )

Hexagonal Boron Nitride   Product Description   *Executive standard: Q/TY.J08.04-2015 *English alias: Boron nitride, white graphite *CAS RN: 10043-11-5 *1. Physical and chemical properties: 1.1    Molecular formula: BN 1.2    Molecular weight: 24.81 (on 1979 international atom weight) 1.3    Structure formula:  1.4    Melting point: 3000℃ 1.5    Mohs′ hardness: 1-2. 1.6    Density: 2.29 g/cm3 1.7    Solubility: Insoluble in water, slightly soluble in hot acid.      1.8    Properties: Hexagonal boron nitride has excellent properties, such as, high electrical insulation, high thermal conductivity, good corrosion resistance and good lubricating ability. In addition, it has corrosion resistant to all melting metals. Its oxidation resistance temperature can reach 1000℃, and can reach 3000℃ when it be used in nitrogen and argon. The shape of hexagonal boron nitride, of which oxidation resistance temperature of can reach 2000℃, is the white bulk after the high-temperature sintering and easy to be machining. *2.

*3. Application: H-BN-A, B, C: The product is medium crystallization, excellent in high temperature and oxidation resistance, small in primary particle size and large in agglomerated size. Because the particles are spherical, they are especially suitable for filling, casting and injection molding. Molding agents and composite ceramics are also easily thermoformed.
H-BN-D: The performance of the product is close to or close to the advanced level of similar foreign products. Because the particle size is similar to that of PTFE and the particle size is uniform, it is especially suitable for high-pressure switch nozzles. At the same time, due to its superior thermal conductivity, it is very suitable for heat-conducting plastic or thermal rubber; and because of its low oxygen content (generally Less than 0.5%), also suitable for special ceramic raw materials.
H-BN-E: The product has high crystallinity and uniform particle size. The high crystallinity of hexagonal boron nitride has better performances than ordinary products in terms of heat conduction, insulation, lubrication, high temperature resistance and resistance to molten metal corrosion. Can be used in a variety of high-end applications, including cosmetics and thermal materials, performance to achieve or close to the advanced level of similar foreign products, can replace imports.
H-BN-F: The product itself has high thermal conductivity, electrical insulation, low dielectric constant, low expansion coefficient and good stability, so it is often used as an additive in the high-end electronics industry. Currently, other application areas of this product are being developed. *4. Safety instructions: Physically inert, but boron nitride powder is toxic by ingestion, inhalation, eye and skin contact, which may cause skin, respiratory system, liver, kidney and the circulatory system damage. Be handled with rubber gloves, a respirator and eye protection. *5 Packing: Aluminum foil bag lined with plastic bag, net weight 1kg per bag. *6. Storage: Stored in a cool and ventilated place. Keep sealed. The shelf life is 12 months after manufactured date. It is still available if the retest results of the properties are qualified after expired date. *7. Transportation: Avoid water, sun-baked and violent collision .Do not transport with strong oxidizers. In addition: We are able to develop custom-made products according to the clients’ requests. Our Services Develop custom-made products according to the clients’ requests and offer OEM service.
