Ammonium Sulphate is a kind of nitrogen fertilizer which can provide N for NPK and mostly used for agriculture. Besides providing the element of nitrogen, it can also provide the element of sulphur for crops, pastures and other plants. Because of its fast release and quick acting, ammonium sulfate is much better than other nitrogen furtillizers such as urea, ammonium bicarbonate, ammonium chloride and ammonium nitrate.
Mainly used for making compound fertilizer, potassium sulfate, ammonium chloride, ammonium persulfate, etc, can also be used for rare earths mining.
Property: White or off-white granule, easily soluble in water. Aqueous solution appears acid. Insoluble in alcohol, acetone and ammonia, Easily deliquescent in the air.
An excellent nitrogenous fertilizer (commonly known as fertilizer field powder) is suitable for general soils and crops. It can make branches and leaves prosperous, improve fruit quality and yield, and enhance crop resistance to disasters. It can be used as base fertilizer, top dressing and seed fertilizer. It can be reacted with salt to produce ammonium chloride, and it reacts with aluminum sulfate to produce ammonium alum, which is used together with boric acid to make refractory materials. Adding electroplating solution can increase the conductivity. It is also a catalyst for food paste color, a nitrogen source for cultivating yeasts in the production of fresh yeast, an acid dye assisting agent, and a leather deashing agent. In addition, it is also used in beer brewing, chemical reagents and battery production. There is also an important role is to extract rare earth, mining ammonium sulfate as raw material, the exchange of rare earth elements in the ore by ion exchange, and then collecting the leachate impurity, sedimentation, pressing, burning after the preparation of rare earth ore, each mining production One ton of rare earth ore needs about 5 tons of ammonium sulfate.
