Ammonium Bifluoride
| Formula | CAS No. | Content |
|---|---|---|
| NH4HF2 | 1341-49-7 | 98.0% min |
It is a colorless rhombus ,granular or flaky crystal, soluble in water, but hardly soluble in alcohol. Its stable liquor is acidity in dry condition. It decomposes in hot water and has poison.
It is used as chemical reagent, glass etchant. aseptic and disinfector, screening agent, flux of metallurgy in fermenting industry .It is also used for pottery and magnesium alloy.
Store in a dry and clean storeroom. Strictly prohibit insolation and rain, prevent damaged.
25Kg net, pack sealed, P.P. woven bags with double PE inners.
What is the main application of Ammonium Bifluoride ?
The industry with the largest usage of ammonium bifluoride is: glass processing (including photovoltaic glass) and electronic semiconductors (including silicon wafers / wafer cleaning and etching). The combined proportion of these two exceeds 65% to 70%; among them, traditional glass etching accounts for approximately 42%, which is the single largest sub-segment.
In the glass processing industry, what are the specific applications of ammonium bi fluoride?
Glass frosted & ground-milled;
Glass etching & Artistic engraving;
Optical glass and lenses have undergone mild etching.
Remove burrs and trim edges of the glass;
Perform anti-reflection and anti-reflective coating treatment on photovoltaic glass;
Clean, descale and remove oxidation from the glass.
What is the difference of the Industrial grade / Electroplating grade / Electronic grade ?
Industrial grade: Cheap, with high impurities, only used for frosted glass and ordinary acid washing.
Electroplating grade: Strictly controlled impurities, ensuring no fogging or pinholes on the coatin.
Electronic grade: Ultra-high purity, metal ions at ppb level, used for silicon wafers, semiconductors, and photovoltaics.
