Boron is mainly used in metallurgy, electronics, medicine, ceramics, nuclear industry, chemical industry, etc., in the form of compounds or as an additive to the alloy.
Executive standard: ①Q/YTY002-2011
English another name: 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: 2550℃
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 300℃and burned if heated to 700℃. 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.

Boron is mainly used in metallurgy, electronics, medicine, ceramics, nuclear industry, chemical industry, etc., in the form of compounds or as an additive to the alloy.
It can be used as a gas scavenger for smelting and melting steel of special alloy steels, as a pilot rod for igniting tubes in the electronics industry, as a control rod in nuclear reactors and as a rocket high-energy fuel
It is an important raw material for the manufacture of high-purity boron halide, and is a raw material for preparing various boride; it can replace and save a large amount of valuable and olefin-deficient metals; boron and its compounds can also be used as catalysts for organic chemical reactions.
