Allgemeine Beschreibung

Ammonium bicarbonate is bicarbonate salt of the ammonium ion. In addition to being a source of ammonia, it is also commonly used as a mild base. Bicarbonate of ammonia appears as granular crystals and is easily soluble in water. In the synthesis of catalysts, ammonium bicarbonate is used.

Anwendung

Ammonium bicarbonate is used:
  • As a mineral fuel to prepare alumina-zirconia nano powders by sol-gel combustion.
  • Precipitating agent in the synthesis of γ-Al2O3 sample (γ-Al2O3-1), that is used for the removal of fluoride from aqueous solution.

An enhanced thermal decomposition of chemical compounds in aqueous solution has been achieved at reduced solution temperatures. The technique exploits hitherto unrecognized properties of a bubble column evaporator (BCE). It offers better heat transfer efficiency than conventional heat transfer equipment.
