English name:Amporphous factor boron

English an additional title:Boron

CAS RN:7440-forty two-eight

1 Physical and chemical houses:

one.1 Elementary image:B

1.2 Atomic bodyweight:ten.eighty one(on 1979 intercontinental atomic bodyweight)

1.3 Melting point:23002C

one.4 Sublimation temperature:2550C

1.five Specific gravity:2.34-two.37

one.6 Solubility: It is undissolved in h2o, hydrochloric acid, ethanol and ethyl ether, but dissolvable in chilly concentrated fundamental answer and decomposed, hydrogen is release at the identical time. It can be oXiHu (West Lake) Dis.dized by concentrated sulfuric acid or nitric acid to boric acid.

one.7 Properties: Boron is on a EPT location in the mid of metallic and nonmetal on the periodic table of components. Its chemical homes are more active because of extremely strong adverse electric power, little atomic radius and centralized nuclear charge. It is stable in regular temperature, oXiHu (West Lake) Dis.dized when heating to 300C,and burned if heated to 700C.It is tasteless and odorless. Its nonmetal house is comparable to silicon. Boron can interact with oxygen, nitrogen, sulfur, halogen or carbon and so on. It can be combined right with a lot of types of metals to form the boronic compounds. Moreover boron can be also reacted with organic and natural compounds to generate some compounds, in which boron is immediately joined to carbon, or oxygen eXiHu (West Lake) Dis.sts between boron and carbon.

Solution Employs

three. Employs:Boron is mostly used in metallurgy, electronics, medicine, ceramics, nulear business and chemical business etc, it is utilised in the kind of compound or is additional in some alloEPTas a addend. It can be utilized in smelting of some EPT alloy steels and as the fuel remover for the melting metal, in the melt away-entraining pole of burning-entraining tube in the sector, in the management stick of atomic reactor, and in the higher-vitality fuels for rocket. It is a EPTant content for producing substantial-pure halogenatedborons, also a materials for generating a selection of boronic compounds. A good deal of noble and unusual metals can be substituted and saved by it. Boron and its compounds can be also employed as the catalyst for some organic and natural chemical reactions, and so on.

four. EPT notes:the solution is deemed toXiHu (West Lake) Dis.c by inhaling and taking in, to inhale it will have an influence on the central anxious method, to take in it will direct to stimulation of abdomen and intestines canal and boron poisoning, to get in touch with with pores and skin or eyes will guide to sligEPT stimulation, should put on basic safety protecting glasses, dustproof gauze mask, rubber gloves for the duration of dealing with it.

5 Deal:Its vacuum-packed in the aluminium foil baggage, in which has been put the plastic bag. Net weigEPT 1kg a bag.

six. Storage:It should be stored in a shady, ventilating and dry storehouse. Its shelf life is one yr. The product can be nevertheless utilized if up to stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd through retest right after the specified date.

7. Transportation:must avoid violent collision, rain drenching, sunning, and cant just take mixed transportation with sturdy oXiHu (West Lake) Dis.dants for the duration of transporting.
