one Physical and chemical houses:
one.one Elementary image:B
one.2 Atomic bodyweight:10.81(on 1979 worldwide atomic fat)
1.three Melting level:23002C
1.4 Sublimation temperature:2550C
one.5 Certain gravity:two.34-two.37
one.six Solubility: It is undissolved in drinking water, hydrochloric acid, ethanol and ethyl ether, but dissolvable in chilly concentrated simple remedy and decomposed, hydrogen is release at the same time. It can be oXiHu (West Lake) Dis.dized by concentrated sulfuric acid or nitric acid to boric acid.
one.seven Homes: Boron is on a EPT spot in the mid of metallic and nonmetal on the periodic table of elements. Its chemical properties are far more active because of quite sturdy damaging electricity, little atomic radius and centralized nuclear demand. It is stable in standard temperature, oXiHu (West Lake) Dis.dized when heating to 300C,and burned if heated to 700C.It is tasteless and odorless. Its nonmetal residence is comparable to silicon. Boron can interact with oxygen, nitrogen, sulfur, halogen or carbon etc. It can be blended immediately with numerous kinds of metals to sort the boronic compounds. Moreover boron can be also reacted with organic and natural compounds to generate some compounds, in which boron is directly joined to carbon, or oxygen eXiHu (West Lake) Dis.sts amongst boron and carbon.

Product Uses
three. Employs:Boron is mostly utilized in metallurgy, electronics, medication, ceramics, nulear market and chemical sector and so on, it is utilised in the form of compound or is extra in some alloEPTas a addend. It can be employed in smelting of some EPT alloy steels and as the gasoline remover for the melting steel, in the melt away-entraining pole of burning-entraining tube in the industry, in the handle adhere of atomic reactor, and in the high-vitality fuels for rocket. It is a EPTant material for creating substantial-pure halogenatedborons, also a material for producing a variety of boronic compounds. A good deal of noble and rare metals can be substituted and saved by it. Boron and its compounds can be also utilised as the catalyst for some natural chemical reactions, and so on.
4. EPT notes:the product is deemed toXiHu (West Lake) Dis.c by inhaling and eating, to inhale it will have an result on the central nervous program, to consume it will lead to stimulation of stomach and intestines canal and boron poisoning, to make contact with with pores and skin or eyes will guide to sligEPT stimulation, need to dress in security protecting eyeglasses, dustproof gauze mask, rubber gloves throughout managing it.
five Bundle:Its vacuum-packed in the aluminium foil baggage, in which has been set the plastic bag. Internet weigEPT 1kg a bag.
6. Storage:It should be stored in a shady, ventilating and dry storehouse. Its shelf lifestyle is 1 year. The merchandise can be even now utilized if up to stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd through retest following the specified date.
seven. Transportation:should stay away from violent collision, rain drenching, sunning, and cant consider blended transportation with powerful oXiHu (West Lake) Dis.dants for the duration of transporting.
