boron definition

  • noun:
    • A soft, brown, amorphous or crystalline nonmetallic element, removed chiefly from kernite and borax and found in flares, propellant mixtures, atomic reactor control elements, abrasives, and difficult metallic alloys. Atomic #5; atomic body weight 10.811; melting point 2,300°C; sublimation point 2,550°C; specific gravity (crystal) 2.34; valence 3. See Table at element.
    • The chemical element (image B) with an atomic few 5; a metalloid
    • A nonmetallic factor happening abundantly in borax. It's paid off with difficulty towards no-cost condition, when it can be acquired in lot of variations; viz., as a substance of a deep olive shade, in a semimetallic form, plus colorless quadratic crystals like the diamond in stiffness as well as other properties.
