Phosphoric acid may be produced by two processes: 1) wet process 2) furnase process. Our product is made by furnase process which minimizes impurities content, particularly suitable for food industry.


Technical grade phosphoric acid can be used to produce variety of phosphates, electrolyte treatment liquids or chemical treatment liquids, refractory mortar with phosphoric acid and inorganic coheretant. It is also used as a catalyst, drying agent and cleaner. In coating industry it is used as a rust-proof coating for metals; As a acidity regulator and nutrition agent for yeast food grade phosphoric acid may be applied to flavors, canned food and light drinks as well as used in wine brewery as a nutrients source for yeast to prevent the reproduction of useless bacteria.
