English title: Boron Nitride
An additional English identify: Boronnitride off white powder
CAS RN: 10043-eleven-5
one. Bodily and chemical homes:
1.1 Molecular weight: 24.eighty one(according to the 1979 worldwide atom bodyweight)
1.two Melting stage: 3000 degree(It is secure for the duration of inert gas)
1.3 Mohs’ scale of hardness: one-two
1.4 Density: two.29g/cm3
one.five Solubility: Insoluble in drinking water.
1.6 Houses: Boron nitride is a most easy new sort of macromolecular materials with equally of hexagonal and cubic crystal styles. It is a sort of solution with high temperature-resisting, corrosion-resisting. High insulating and great lubricity. Its oXiHu (West Lake) Dis.dation-resisting temperature can get to one thousand degree, and possesses also excellent lubricity in higher temperature, so it is a type of good large-temperature reliable lubricants. It has the very EPTful capability of neutron-absorbing. Its chemical properties are stable. It has really EPTful ability of neutron-absorbing, Its chemical properties are secure, It has reasonably excellent corrosion-resisting potential for different inorganic acids, alkali, salt solutions and natural and organic solvents. It current chemical inert for almost every single melting metals. Its resistance to high temperature can achieve 2000 degree, and can reach 2800 diploma when use it in nitrogen and argon. Its forming products have the fantastic house easy to machining. Its humid resistance is really very good. It has not only low coefficient of warmth expansion, but also heat conductivity. It is equally great warmth conductor and standard electric powered insulator.
2. Makes use of: Boron nitride could be extensively utilised in the EPT departments of petroleum, chemical, EPTry, electronics, electric powered EPT, textiles, nuclear, space and other. It could be utilised as the additives of this kind of polymers as plastic resin and so on, the insulators of substantial pressure higher-frequency level and plasma are the reliable-period combined content of semiconductor, the structural content of atomic reactor, the EPT content for stopping neutron radiation, the strong lubricant and wear-resisting substance and benzene absorbent and many others. The combination of EPTium diboronide, EPTium nitride and boron oXiHu (West Lake) Dis.de, which is acquired by very hot-urgent forming of boron nitride and EPTium, is the catalyst for dehydrogenation of organic and natural matters, rubber synthesis and platforming. In substantial temperature, it could be used as the specific supplies of electrolysis and resistance, and scorching sealing dry-heating agent of transistor. It is the content of aluminium evaporating container.
The boron nitride powEPTcould be also used as the stickiness-proof agent for glass microbead, the demoulding agent for glass and steel forming. The boron nitride manufactured overhard materials could be used for making the high-speed chopping tool and the little bit of geological prospecting and petroleum.
3. EPT notes: Boron nitride is bodily inert. Its EPT is regarded dangerous to XiHu (West Lake) Dis.Hu (West Lake) Dis.n. It will hurt one’s overall health by swallowing, inhaling, pores and skin-connecting or eye-connecting. Swallowing and respiratory will direct to unnormal to skin, respiratory system, liver, kidney and the circulatory system. Pores and skin-contacting or eye-getting in touch with will all give increase to stimulation. Should use protection-protective eyeglasses, dustproof gauze mask, rubber gloves for the duration of dealing with it.
4. Package: It is vacuum-packed in aluminium foil bag, in which is place plastic bag. Internet weigEPT 1kg a bag.
five. Storage: It ought to be stored in a shady, ventilating and dry storehouse. Its shelf lifestyle is one particular year. The product can be nevertheless utilised if up to stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd by way of retest after the specified day.
6. Transportation: Ought to avoid raining, dampening and can not get combined transportation with sturdy oXiHu (West Lake) Dis.dants in the course of transporting.
