B Boron Powder CAS 7440-42-8 used in metallurgy, electronics and boron ceramics
Brief Description of  Boron  Powder

Boron is a chemicals element with symbol B and atmic number 5. 

Produced entirely by cosmic ray spallation  and supernovae and not by stellar nucleosynthesis.

It is a low-abundance element in the Solar system  and in the  Earth’s crust. 

Boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate minerals.

These are mined industrially as evaporites,  such as borax and kernite.

Application of Boron Powder 

1. The major global industrial-scale use of boron compounds (about 46% of end-use) is in production of glass fiber for boron-containing insulating and structural  fiberglasses, especially in Asia.

2. About 15% of global boron is used in boron ceramics, including super-hard materials discussed below.

3. 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.

4. It can be used in smelting of some special alloy steels and as the gas remover for the melting steel

5 . 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.
