Ammonium Hydrogen Fluoride in Manufacturing

NH4HF2 is the chemical component of Ammonium hydrogen fluoride. It is been used in metal surface treatment, aluminium anodization, manufacture of wood preservation, building protection, natural gas/ mineral oil drilling, glass processing, cleaning of industrial plants and electronic industry.

In the Global Ammonium hydrogen fluoride industry, fluorine and inorganic compounds play a major role. They are not just used for the manufacturing process but while processing and finishing of aluminium.

Introduction of cryolite made the manufacturing of aluminium possible on a commercial scale.

Using cryolite decreases the temperature of the smelting flux electrolysis. Cryolite is a major component of electrolyte. Current commercial additions to electrolytes are used as aluminium fluoride, calcium fluoride, and lithium fluoride.

These improve the efficiency and increase the conductivity of electrolytes using energy. Aluminium produced will have the purity of 99.5- 99.9%. Though cleaning and improvement of aluminium are carried out by the three-layer-fused-salt electrolysis. This process is the only commercial process for the production of pure aluminium.

Applications of Ammonium Hydrogen Fluoride

According to a popular study, there has been a significant decline in the Ammonium Hydrogen Fluoride market due to this impact of Covid-19. This component is majorly used for the following purposes:

  1. Glass processing: for matt etching
  2. Metal surface treatment: as an essential component of bright indigo baths for etching and cleaning of non-ferrous metal pieces
  3. Mineral oil / natural gas drilling: as an aid for drilling through silicate rocks
  4. Cleaning of industrial plants: as a component in cleaning and disinfecting solutions, e.g. in power stations
  5. Building protection: As a component in cleaning agents
