AMMONIUM Bifluoride Crystal
Part No. RXSOL-81-6212-040
Ammonium Hydrogen Fluoride
If the acid used in the working mixture of hydrofluoric acid (45%), it would take 1.55 times more than if we use a dry ammonium bifluoride.
Key Technical Details
| Part number | RXSOL-81-6212-040 |
|---|---|
| Generic name | Ammonium Hydrogen Fluoride |
| Standard packing | 25.00 |

| Supply locations | Ammonium Bifluoride Technical Grade ABF dealer, supplier in Mumbai, Kandla, Chennai, Kolkata, Visakhapatnam, Dubai, Sharjah, Abudhabi, Fujairah, Muscat Barka, Sohar, Oman, UAE Middle East, Canada Difference between HF and ABF uses. HF 70% acid Handling is very dificult also makes hole in glove finger tips. While ABF never had a burn with solid ABF, however avoid to use by bare hands. If comes in contace quickly rinse with free flowing water. Always handle ABF with care and wear eye and skin glove protection during mixing or using, and never handle ABF with your bare hands. Handling Procedure of ABF and HF Calcium gluconate gel is helpfull cream to protect from HF / ABF burns to the skin. On contact immediately flush the contact part with cupious amount of water and applying calcium gluconate gel followed by immediate medical attention. USES of ABF : As a Aluminum brightener use 28% (wt) ammonium bifluoride to 72% (wt) water. To Etch Glass use 1 Kilo ammonium bifluoride and 2 liters sulfuric acid in 3 gallons water bath. |
Ammonium Bifluoride successfully replaces the traditional, but a dangerous and aggressive material - hydrofluoric acid, which is very aggressive, corrodes many materials, causing severe burns, releases harmful to breathe fumes. Ammonium bifluoride use instead of hydrofluoric acid is safer for use, storage and transportation and is less harmful, and reduce your costs by 10 - 15%.

Analysis
Appearance : White crystalline solid (Orthorhombic crystals)
NH4HF2 : 98.76%*
(NH4)2SO4 : 0.05%
(NH4)2SiF6 :0.20%
Moisture :0.59%
Solubility in water : 60.2 g at 20°C and 156.4g at 60°C per 100ml of water
Solubility in HCl : 10% (w/v) sample is soluble in 15% (w/w) of HCl at 25°C
*Assay: Weigh accurately about 1.0gm of Ammonium bi fluoride sample. Dissolve it in 100ml distilled water. Titrate with about 1N NaOH. Use Phenolphthalein as indicator. End point is Colourless to Pink.
% acidity as HF = A / B
1st calculate Consumption of NaOH, B.R. X Normality of NaOH X 0.02 X 100 = A
Then Divided the result with " Weight of the sample " = B
%NH4HF= %acidityasHFx57 / 20
Ammonium bifluoride is a white crystal salt chemically when ammonium bifluoride comes in contact with water resulting with the formation of HF. It is used to brighten aluminum and other metals.
