It is mainly used as a glass etchant, preservative, solvent for making metallic beryllium from beryllium oxide, chemical reagent, cleaning agent for boiler water supply system and steam generation system, disinfectant for fermentation industry, surface treatment agent for silicon steel plate, oxidant for manufacturing ceramics and aluminum-magnesium alloy, organic synthetic fluorination agent, electroplating solution, solvent for extracting rare elements, acidification treatment agent for oilfield sand and gravel, etc. Ammonium bifluoride is usually prepared by liquid phase method. During the preparation process, a centrifuge is needed to centrifuge the mixed solution containing ammonium bifluoride and ammonium fluoride.
