High and Pure CAS 7440-42-8 nano B powder boron powderProduct Description
Features of boron powder:
Pure boron powder is brown or black brown odorless powder with active chemical character. Boron compounds were known for thousands of years ago, but the pure boron was first discoverd until 1808 by two French chemists: Sir Humphry Davy and J.L Gay-Lussac. The name Boron originates from a combination of carbon and the Arabic word 'buraqu meaning borax. It exists in nature mainly by borate minerals. Heating borax with carbon is the key process to obtain boron.
