Cas No. :10043-11-5
Quantity: 1Kilograms Specs:Purity:99% Appearance :White loose powder Price:45 USD Kilograms Payment Method: T/T advance,Western Union, Boron Nitride Executive standard： Enterprise standard English name：Boron Nitride Another English name：Boronnitride off white powder CAS RN：10043-11-5 1. Physical and chemical properties： 1.1 Molecular formula： 1.2 Molecular weight：24.81(according to the 1979 international atom weight) 1.3 Appearance ：White loose powder 1.4 Melting point：3000℃(It is stable during inert gas) 1.5 Mohs’ scale of hardness：1-2 1.6 Density：2.29g/cm3 1.7 Solubility： insoluble in water. 1.8 Properties：Boron nitride is a most simple new type of macromolecular materials with both of hexagonal and cubic crystal shapes. It is a kind of product with high temperature-resisting, corrosion-resisting .high insulating and good lubricity.Its oxidation-resisting temperature can reach 1000℃, and possesses also good lubricity in high temperature, so it is a kind of good high-temperature solid lubricants. It has very powerful capacity of neutron-absorbing,Its chemical properties are stable, It has fairly good corrosion-resisting capacity for various inorganic acids, alkali, salt solutions and organic solvents. It present chemical inert for nearly every melting metals. Its resistance to high temperature can reach 2000℃,and can reach 2800℃ when use it in nitrogen and argon. Its forming products possess the fine property easy to machining. Its humid resistance is very good. It has not only low coefficient of heat expansion, but also heat conductivity. It is both good heat conductor and typical electric insulator. 2. Technical indexes Term 1st grade 2nd grade 3rd grade Boron Nitride ％ ≥99 ≥98 ≥97 Free Boron ％ ≤0.5 ≤0.5 ≤0.5 Granularity 0.17-5 0.17-5 0.17-5 Appearance White loose powder 3. Uses：Boron nitride could be extensively used in the industrial departments of petroleum, chemical, machinery, electronics, electric power, textiles, nuclear, space and other. It could be used as the additives of such polymers as plastic resin and so on, the insulators of high pressure high –frequency point and plasma are the solid-phase mixed material of semiconductor, the structural material of atomic reactor, the packing material for preventing neutron radiation, the solid lubricant and wear-resisting material and benzene absorbent etc. The mixture of titanium diboronide, titanium nitride and boron oxide, which is obtained by hot-pressing forming of boron nitride and titanium, is the catalyst for dehydrogenation of organic matters, rubber synthesis and platforming. In high temperature, it could be used as the specific materials of electrolysis and resistance, and hot sealing dry –heating agent of transistor. It is the material of aluminium evaporating container. The boron nitride powder could be also used as the stickiness-proof agent for glass microbead, the demoulding agent for glass and metal forming. The boron nitride made overhard materials could be used for making the high-speed cutting tool and the bit of geological prospecting and petroleum. 4. Safety notes: Boron nitride is physical inert. Its power is considered harmful to human. It will harm one’s health by swallowing, inhaling, skin-connecting or eye-connecting. Swallowing and breathing will lead to unnormal to skin, respiratory system, liver, kidney and the circulatory system. Skin-contacting or eye-contacting will all give rise to stimulation. Should wear safety-protective glasses, dustproof gauze mask, rubber gloves during handling it. 5. Package: It is vaccum-packed in aluminium foil bag, in which is put plastic bag. Net weight 1kg a bag. 6. Storage:It should be stored in a shady, ventilating and dry storehouse. Its shelf life is one year. The product can be still used if up to standard through retest after the specified date. 7 .Transportation:Should avoid raining,dampening and can’t take mixed transportation with strong oxidants during transporting. |
