3. Uses :
Boron is mainly used in metallurgy, electronics, medicine, ceramics, nulear industry and chemical industry etc, it is used inthe form of compound or is added in some alloys as a addend. It can be used in smelting of some special alloy steels and as the gas remover for the melting steel, in the burn-entraining pole of burning-entraining tube in the electric industry,of boronic compounds. A lot of noble and rare metals can be substituted and saved by it. Boron and its compounds can bealso used as the catalyst for some organic chemical reactions, and so on.
