Colorless crystals or white particles. No smell. Decomposition above 280ºC. Solubility in water: 70.6g at 0ºC, 103.8g at 100ºC. Insoluble in ethanol and acetone. A 0.1mol/L aqueous solution has a pH of 5.5. The relative density is 1.77. Refractive index 1.521. Ammonium sulfate is mainly used as a fertilizer and is suitable for a variety of soils and crops. It can also be used in textile, leather, medicine and so on.
An excellent nitrogen fertilizer (commonly known as fertilizer powder), suitable for general soil and crops, can make branches and leaves grow vigorously, improve fruit quality and yield, enhance crop resistance to disasters, can be used as base fertilizer, topdressing and seed fertilizer. It can produce ammonium chloride by double decomposition reaction with salt, and ammonium alum by action with aluminum sulfate, and make refractory materials together with boric acid. Adding electroplating solution can increase electrical conductivity. It is also the catalyst of food sauce color, the nitrogen source of yeast culture in the production of fresh yeast, acid dye dyeing aid, leather deashing agent. In addition, it is also used in beer brewing, chemical reagents and battery production. Another important role is the mining of rare earth, mining with ammonium sulfate as a raw material, the use of ion exchange form to exchange the rare earth elements in the ore, and then collect the leaching solution to remove impurities, precipitation, pressing, burning is rare earth raw ore.
