Ammonium sulfate is an inorganic substance with the chemical formula (NH4) 2SO4. It is a colorless crystal or white particle with no odor. Decompose above 280 ºC. Solubility in water: 70.6g at 0 ºC and 103.8g at 100 ºC. Insoluble in ethanol and acetone. The pH of a 0.1mol/L aqueous solution is 5.5. The relative density is 1.77. Refractive index 1.521. Ammonium sulfate is mainly used as fertilizer and is suitable for various soils and crops. It can also be used in textile, leather, medicine and other fields.
purpose
An excellent nitrogen fertilizer (commonly known as fertilizer field powder) suitable for
General soil and crops can promote vigorous growth of branches and leaves, and improve fruit quality
Enhance crop resistance to disasters by improving quality and yield,
Can be used as base fertilizer, topdressing, and seed fertilizer. Can undergo double decomposition with salt
Reaction produces ammonium chloride, which reacts with aluminum sulfate to form ammonium alum,
Manufacturing refractory materials together with boric acid and other materials. Adding it to the plating solution can
Increase conductivity. Also a catalyst for food sauce color, fresh yeast
Nitrogen source for cultivating yeast in production, acid dye assisted dyeing
Agent, leather dust remover. In addition, it is also used for beer brewing and fermentation
Learn reagent and battery production, etc. Another important role is
Mining rare earths, using ammonium sulfate as raw material and ion exchange
Exchange the rare earth elements in the mineral soil and collect them for leaching
After removing impurities from the liquid, settling, pressing, and burning, it becomes rare earth raw ore,
Approximately 5 tons of ammonium sulfate are required to mine and produce 1 ton of rare earth ore
