Ammonium Carbonate Lumps

Ammonium Carbonate Lumps refer to the solid, block, or crystalline form of ammonium carbonate, a white or translucent salt with a strong ammonia odor. These lumps are commonly used in laboratory and industrial applications where a convenient and easily handled source of ammonia or a leavening agent is needed.

Molecular Weight: 96.09 g/mol.​

Solubility: Free flowing and readily soluble in water.​

pH (10% solution): Typically around 9.0.​

Decomposition: Decomposes upon heating to release ammonia and carbon dioxide gases.​

Typical Applications

Used as a leavening agent in baked goods and as baker's ammonia (especially in European recipes), helping to create a light, porous texture.​

Acts as a pH adjuster in laboratory solutions and industrial processes.​

Constituent of smelling salts due to its strong odor and ability to volatilize quickly.​

Used as a source of ammonia in metal treatment and polymer manufacture.​

Employed in photographic lens cleaning agents and some analytical chemistry environments.​

Occasionally used as bait in agricultural applications to trap certain pests.​

Safety and Handling

Non-combustible, but should be handled in well-ventilated areas due to possible ammonia release.​

May cause mild irritation if inhaled or ingested in large amounts; classified as harmful if swallowed in concentrated quantities.​

Packages are typically supplied in plastic or polypropylene sacks ranging from 25 kg to 1000 kg for industrial use.​
