Government stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd: EPTrprise stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd
English name: Boron Nitride
An additional English name: Boronnitride off white powder
CAS RN: 10043-eleven-five
1. Physical and chemical homes:
one.1 Molecular fat: 24.81(according to the 1979 international atom excess weight)
1.two Melting stage: 3000 degree(It is steady during inert fuel)
one.three Mohs’ scale of hardness: 1-2
1.four Density: two.29g/cm3
1.five Solubility: Insoluble in h2o.
one.six Houses: Boron nitride is a most simple new kind of macromolecular materials with both of hexagonal and cubic crystal shapes. It is a type of solution with higher temperature-resisting, corrosion-resisting. High insulating and very good lubricity. Its oXiHu (West Lake) Dis.dation-resisting temperature can attain 1000 degree, and possesses also excellent lubricity in large temperature, so it is a sort of great higher-temperature solid lubricants. It has the very EPTful potential of neutron-absorbing. Its chemical properties are secure. It has really EPTful capacity of neutron-absorbing, Its chemical homes are stable, It has fairly very good corrosion-resisting potential for various inorganic acids, alkali, salt solutions and natural solvents. It current chemical inert for practically every melting metals. Its resistance to substantial temperature can get to 2000 degree, and can attain 2800 diploma when use it in nitrogen and argon. Its forming items have the wonderful home effortless to machining. Its humid resistance is quite good. It has not only minimal coefficient of warmth expansion, but also heat conductivity. It is both great heat conductor and standard electrical insulator.
two. Utilizes: Boron nitride could be extensively utilized in the EPT departments of petroleum, chemical, EPTry, electronics, electric EPT, textiles, nuclear, area and other. It could be utilized as the additives of these kinds of polymers as plastic resin and so on, the insulators of high pressure higher-frequency point and plasma are the reliable-period mixed material of semiconductor, the structural content of atomic reactor, the EPT substance for avoiding neutron radiation, the reliable lubricant and wear-resisting substance and benzene absorbent and so forth. The combination of EPTium diboronide, EPTium nitride and boron oXiHu (West Lake) Dis.de, which is obtained by sizzling-urgent forming of boron nitride and EPTium, is the catalyst for dehydrogenation of natural matters, rubber synthesis and platforming. In substantial temperature, it could be employed as the particular supplies of electrolysis and resistance, and hot sealing dry-heating agent of transistor. It is the content of aluminium evaporating container.
The boron nitride powEPTcould be also employed as the stickiness-proof agent for glass microbead, the demoulding agent for glass and metal forming. The boron nitride created overhard supplies could be utilized for creating the high-velocity slicing instrument and the little bit of geological prospecting and petroleum.
three. EPT notes: Boron nitride is physical inert. Its EPT is regarded as damaging to XiHu (West Lake) Dis.Hu (West Lake) Dis.n. It will harm one’s well being by swallowing, inhaling, pores and skin-connecting or eye-connecting. Swallowing and respiratory will lead to unnormal to skin, respiratory technique, liver, kidney and the circulatory program. Pores and skin-making contact with or eye-getting in touch with will all give increase to stimulation. Should dress in security-protecting eyeglasses, dustproof gauze mask, rubber gloves during managing it.
4. Deal: It is vacuum-packed in aluminium foil bag, in which is put plastic bag. Web weigEPT 1kg a bag.
five. Storage: It ought to be saved in a shady, ventilating and dry storehouse. Its shelf life is 1 year. The solution can be nevertheless utilized if up to stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd through retest right after the specified date.
6. Transportation: Must steer clear of raining, dampening and can not consider mixed transportation with sturdy oXiHu (West Lake) Dis.dants in the course of transporting.
