The elemental boron is black or dark brown powder, and the formation of boron trioxide film in the air prevents the internal boron oxidation. It can react with fluorine at room temperature and is not corroded by hydrochloric acid and hydrofluoric acid aqueous solution. Boron is insoluble in water, and the powdered form of boron is soluble in boiling nitric and sulfuric acids, as well as most molten metals such as copper, iron, manganese, aluminum, and calcium.
