Fungsi Ammonia Bicarbonate
Chemical Formula: AC
CAS Number:1066-33-7
HS CODE:2836994000
Physical state: White powder
Assay:99 – 100.5%
Ammonium bicarbonate
ABC is chemically unstable and decomposes readily upon heating, generating ammonia, carbon dioxide, and water. Its aqueous solution is weakly alkaline and reacts with acids to release carbon dioxide. As a carbonate, it produces bubbles with strong acids and may release ammonia when reacting with alkalis. Slow decomposition occurs even at room temperature, emitting a pungent odor of ammonia.

Ammonium bicarbonate is commonly used as a foaming agent in the chemical and materials industries. For instance, in the production of foam plastics, sponge rubber, and fire-extinguishing agents, its property of readily decomposing upon heating to release gases is utilized to form tiny bubbles within the polymer matrix. This process enables the manufacture of low-density, lightweight porous materials.
