Common Uses:
- Soil Enrichment: Ammonium sulfate is primarily employed as an artificial fertilizer, especially in alkaline soils. Upon introduction to damp soil, it releases ammonium ions, which mildly acidify the ground, thus enhancing its pH balance. Additionally, it provides essential nitrogen for plant growth. Its slow dissolution rate makes it an economical choice than other synthetic fertilizers.
- Herbicide: Due to its ability to scorch plant leaves, ammonium sulfate is also used as an herbicide. It can either kill plants directly or weaken them, facilitating easier removal.
- Printed Circuit Boards: Manufacturers utilize ammonium sulfate to produce printed circuit boards.
- Flame Retardants: Its incorporation in flame retardant materials is due to its capability to lower combustion temperatures and increase the formation of residues or chars.
- Baking: Ammonium sulfate activates yeast, aiding in the leavening process, essential for industrially produced bread.
- Food Additive: A versatile food additive enhances various culinary processes.
- Vaccine Development: In vaccine production, particularly for vaccines like DTap (Diphtheria, Tetanus, and Pertussis), ammonium sulfate plays a crucial role during the purification process.
