Ammonium bicarbonate is widely used in the food industry as a leavening agent in baking. It helps baked goods like cookies, crackers, and biscuits rise by releasing carbon dioxide gas when heated. It is also employed in the production of ceramics and plastics as a blowing agent, aiding in the creation of lightweight materials. In agriculture, it serves as a nitrogen source in fertilizers to promote plant growth. Additionally, it is utilized in fire extinguishers to suppress flames by releasing non-flammable gases. Its mild abrasive properties make it suitable for use in cleaning products for delicate surfaces.
