■ Performance Brief
White orthorhombic crystals in the air easily deliquescence, easily soluble in cold water. Solution is strongly acidic and can corrode glass. Toxic.
■ Uses
Mainly used in the production of frosted glass etchant (hydrofluoric acid and used), used as a chemical agent, disinfection and antiseptic fermentation industry, metal beryllium beryllium oxide surface treatment agent solvents and silicon steel sheet is also used in the manufacture of cleaning ceramic, magnesium alloy, boiler feed water system and steam generation system descaling. And acidification oil sands is also used as alkylation isomerization catalyst component.
