詳細

詳細

HF is a colorless inorganic acid. Hydrogen fluoride may be formed by reacting calcium fluoride and sulfuric acid at 200^oC. The fluoride in the acid has very high affinity to silicon, making it useful in etching or removal of silicon.[1]

アプリケーション

Industrial uses of HF include etching or polishing glass, ceramics and silicon surfaces.[1] HF may be used to etch silica capillaries for it behave as a filter and an integrated nanofluidic device for the stacking of DNA and proteins.[2] Dentin and ceramic inlays may be etched with HF for better adhesive bonding.[3][4] Nanohydroxyapatite was etched with 0.5%HF prior to measuring its morphological and mechanical properties.[5]
