Ammonium bicarbonate CAS#1066-33-7
N-rich Fertilizer ： Nitrogen-containing, ideal for agricultural use.
High Water Solubility : Easily dissolves in water, facilitating application.
Alkaline Solution : Aqueous solution is weakly alkaline, beneficial for soil pH balance.
Controlled Decomposition : Decomposes gradually at room temperature, releasing nutrients slowly.
Product Overview: Ammonium Bicarbonate (CAS 1066-33-7)
Ammonium Bicarbonate is a vital nitrogenous chemical fertilizer, scientifically termed as ammonium hydrogen carbonate and popularly known in agriculture as "gas fertilizer." It appears as white powder or crystalline blocks with a faint ammoniacal odor. With a relative density of 1.58 and a melting point of 107.5°C (under rapid heating), it is highly soluble in water, creating a mildly alkaline solution, yet remains insoluble in ethanol and acetone.
Due to its hygroscopic nature, it tends to absorb moisture and agglomerate. Chemically, it is characterized by its relative instability at room temperature, where it gradually decomposes into carbon dioxide, ammonia, and water. This decomposition rate accelerates significantly under conditions of elevated temperature or high humidity, ensuring rapid nutrient release.
