OVERVIEW

Electronic Grade Hydrofluoric Acid

Formula: HF                      

CAS No. 7664-39-3  

Division Of Class: 8.1, corrosives presenting acidic properties 

Physical and chemical properties: The formula is HF, and the molecular weight is 20.01, it is a kind of colorless and transparent liquid, and the relative density is around 1.15-1.18. It can have a reaction with the normal metal, metallic oxide and hydroxide, generating all kinds of salts. With high corrosivity, it can erode glass and silicate, generating gaseous silicon tetrafluoride. High purity hydrofluoric acid can be used as a highly acid detergent and corrodent, which can also be used with nitric acid, glacial acetic acid, hydrogen peroxide and ammonium hydroxide and etc, with a certain proportion. 

Application range: Hydrofluoric acid can be applied in solar photovoltaic, LCD, and semiconductor industries, mainly playing a role in surface cleaning of silicon wafers and cleaning and etching in the chip manufacturing process. Besides, it can also be an analytical reagent, the industrial chemical reagent in atomic energy and making high purity chemicals containing fluorine. Spec.:
