Rhenium is a rare silver white high melting point metal, with a melting point ranking third among all elements (tungsten and carbon in the first two), a boiling point ranking first, and a density ranking fourth (platinum, iridium, and osmium in the first three). Metal rhenium is hard, wear-resistant, and corrosion-resistant. Rhenium is stable in the air and vaporizes with sulfur at high temperatures to synthesize rhenium disulfide, which forms halides with fluorine, chlorine, and bromine. Rhenium is insoluble in hydrochloric acid, but soluble in nitric acid and hot concentrated sulfuric acid. Rhenium does not interact with hydrogen or nitrogen, but can absorb hydrogen gas. Rhenium is a rare element with a content of 10 ^ (-7)% in the crust, mainly present in molybdenite. Nowadays, rhenium and its alloys are widely used in fields such as aerospace, electronics, and petrochemicals.
