Description
Ammonium Bifluoride (Ammonium Hydrogen Fluoride, NH₄HF₂)
Ammonium Bifluoride, also named ammonium acid fluoride, chemical formula NH₄HF₂, CAS No.1341-49-7, UN1727. It is white transparent flaky crystal with slight acidic odor, easily deliquescent in air, highly soluble in cold water, and the aqueous solution releases mild hydrofluoric acid to corrode silicate materials like glass and ceramic抖音百科.
Compared with liquid hydrofluoric acid, solid ammonium bifluoride features convenient storage, transportation and dosage control, low volatile fume, widely used as etching & cleaning auxiliary across multiple industrial fields.
Core Application Industries
- Glass & Crystal Decoration Industry Main raw material for glass frosting cream, pattern engraving, mirror matte treatment, craft crystal and optical glass surface texturing. Produces smooth uniform frosted effect without rough sandblasting traces.
- Ceramic & Sanitary Ware Manufacturing Clean surface silica impurities on ceramic green body before glazing; remove residual mineral scale, improve glaze adhesion and smooth firing effect. Also used as auxiliary opacifier for low-temperature glaze formula.
- Metal Surface Treatment Pickling & brightening agent for aluminum alloy, stainless steel, silicon steel plate; dissolve surface oxide film, welding discoloration and rust stains, enhance coating/anodizing adhesion.
- Industrial Boiler & Pipeline Cleaning Descaling agent for steam boilers, heat exchangers and cooling pipes, eliminate silicate hard water scale efficiently without heavy corrosion to metal base material.
- Chemical Synthesis & Auxiliaries Key fluorine source to produce sodium fluorosilicate, cryolite and other fluoride salts; used as wood preservative, textile rust remover and oil well acidizing additive.
Our 99% industrial grade ammonium bifluoride features low iron, sulfate and heavy metal impurities, uniform crystal particle size, good water solubility, stable etching speed batch by batch for continuous mass production.
