Amorphous Elemental Boron

Government stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd: Q/YTY002-2011

English alias: Boron

CAS RN: 7440-42-eight

1. Physical and chemical qualities:

1.1 Elementary symbol: B

1.two Atomic bodyweight: 10.eighty one(on 1979 global atomic excess weight)

one.3 Melting stage: 2300 plusmn2 ordmC

one.four Sublimation temperature: 2550 ordmC

one.5 Distinct gravity: two.34-2.37

one.six Solubility: Insoluble in water, ethanol, ethyl ether and hydrochloric acid, but dissolved in cold concentrated simple resolution and decomposed Htwo at the identical time. It can be oXiHu (West Lake) Dis.dized by concentrated sulfuric acid or nitric acid to boric acid.

one.seven Properties:

Boron is between metal collection with nonmetal collection on the periodic table of aspects. As its sturdy electronegative, small atomic radius, and centralized nuclear charge, the chemical qualities of it are reactive. It is stable in regular temperature, but it is oXiHu (West Lake) Dis.dized when heated to 300 ordmC and burned if heated to seven hundred ordmC. It is tasteless and odorless.

Its nonmetal home is comparable to silicon. In high temperature, boron can respond with oxygen, nitrogen, sulfur, halogen or carbon, and so on. It can be mixed immediately with a lot of sorts of metals to sort boride. Moreover, boron can be also reacted with organic compounds to synthesize some compounds, in which boron is immediately joined to carbon, or oxygen eXiHu (West Lake) Dis.sts amongst boron and carbon.

three. Application: Boron has been employed mostly in metallurgy, electronics, medication, ceramics, nuke sector and chemical business and so forth, and it has been used in the sort of compound or as a additive in alloys. It can be utilised in smelting of some EPT alloy steels and as the gasoline scavenger for the melting steel, in the ignitor of igniton in the electric powered market, in the management rod of atomic reactor, and as the high-vitality fuels for rocket. It has been as an EPTant material for manufacturing high-purity of halogenated boron and a raw material for a variety of borides. A lot of exceptional noble metals can be substituted and saved by it. Boron and its compounds can be also utilised as the catalyst of some natural and organic chemical reactions, etc.

4. EPT guidelines: ToXiHu (West Lake) Dis.c by ingestion and inhalation. The central anxious technique is motivated by ingestion, gastrointestinal tract is stimulated by inhalation and boron poisoning. Eyes bear sligEPT stimulation as nicely. Procedure need to be set up with rubber gloves, a respirator and eye protection by putting on protecting clothes.
