3. Uses : Boron is mainly used in metallurgy, electronics, medicine, ceramics, nulear industry and chemical
industry etc, it is used in the 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 be
also used as the catalyst for some organic chemical reactions,
and so on.
