Hydrofluoric acid is aqueous solution of hydrogen fluoride. It's colorless and transparent, having strong and irritative smell and causticity. It can pickling such materials containing SiO 2 as glass quickly. Hydrofluoric acid can’t undergo the reduction reaction and oxidation reaction.With deadly poisonous. Uses:It's widely used in national defense and civil industry, and it is a base product in fluoride industry, It can produce fluoride, freon, fluoroplastics and alky lation contact agent in atomic energy and semiconductor industry. It is also used in metallic surface treatment, glass etching, ceramics treatment and element F production. Chemical constituent and physical properties are all according with national standardGB 7744-2008.
