• Ammonium sulfate Wikipedia

    Dry, powdered ammonium sulfate may be formed by spraying sulfuric acid into a reaction chamber filled with ammonia gas. The heat of reaction evaporates all water present in the system, forming a powdery salt. Approximately 6000M tons were produced in 1981. Ammonium sulfate also is manufactured from gypsum (CaSO 4 ·2H 2 O).
