Boron CAS 7440-42-8 is a trivalent non-metallic element that occurs abundantly in the evaporite ores borax and ulexite. Boron is never found as a free element on Earth. Boron appears as charcoal-grey pieces or black powder or as crystalline; is a very hard, black material with a high melting point; and exists in many polymorphs.

Boron with CAS 7440-42-8 is used to harden metals and as an oxygen scavenger for copper and other metals. It is used as a reinforcing material for composites. Boron filaments are used for lightweight but highstrength building materials for aerospace structures, golf clubs, and fishing rods. Amorphous boron can produce a green flare, and is therefore useful in pyrotechnic flares.
