Amorphous Elemental Boron
Executive standard: Q/YTY002-2011
English alias: Boron
CAS RN: 7440-42-8
1. Physical and chemical properties:
1.1 Elementary symbol: B
1.2 Atomic weight: 10.81(on 1979 international atomic weight)
1.3 Melting point: 2300±2�
1.4 Sublimation temperature: 2550â„?
1.5 Specific gravity: 2.34-2.37
1.6 Solubility: Insoluble in water, ethanol, ethyl ether and hydrochloric acid, but dissolved in cold concentrated basic solution and decomposed H2 at the same time. It can be oxidized by concentrated sulfuric acid or nitric acid to boric acid.
1.7 Properties:
Boron is between metal series with nonmetal series on the periodic table of elements. As its strong electronegative, small atomic radius, and centralized nuclear charge, the chemical properties of it are reactive. It is stable in normal temperature, but it is oxidized when heated to 300â„?and burned if heated to 700â„? It is tasteless and odorless.
Its nonmetal property is similar to silicon. In high temperature, boron can react with oxygen, nitrogen, sulfur, halogen or carbon, etc. It can be combined directly with many sorts of metals to form boride. Moreover, boron can be also reacted with organic compounds to synthesize some compounds, in which boron is directly joined to carbon, or oxygen exists between boron and carbon.

3. Application: Boron has been used mainly in metallurgy, electronics, medicine, ceramics, nuke industry and chemical industry etc, and it has been used in the form of compound or as a additive in alloys. It can be used in smelting of some special alloy steels and as the gas scavenger for the melting steel, in the ignitor of igniton in the electric industry, in the contro |
