Products Description
Phosphorous acid is in Colorless, transparent and syrupy liquid or rhombic crystalline;Phosphorus acid is odorless and tastes very sour; its melting point is 42.35℃ and when heated to 300℃ phosphorous acid will become into metaPhosphoric Acid; its relative density is 1.834 g/cm3;phosphoric acid is easily soluble in water and resolves in ethanol; Phosphate acid may irritate human skin to cause phlogosis and destroy the issue of human body; phosphorus acid shows corrosiveness being heated in ceramic vessels; phosphate acid has got hydroscopicity.
Phosporic Acid Uses :
Technical grade Phosphoric Acid may be used to produce variety of Phosphates, electrolyte treatment liquids or chemical treatment liquids, refractory mortar with phosphoric acid and inorganic coheretant.Phosporic acid is also used as a catalyst, drying agent and cleaner. In coating industry phosphoric acid 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.

Application
Phosphoric Acidused in removing dust from the metal surfaces Used as rust converter by bringing it in direct contact with a rusted iron, or steel tools and other surfaces that are rusted. It is helpful in cleaning the mineral deposits, cement nous smears and hard water stains. Used to acidify the foods and beverages such as colas. Phosphoric Acid is an important ingredient in over the counter medications to combat nausea. Phosphoric Acid is mixed with zinc powder and forms zinc phosphate, and it is useful in temporary dental cement. In orthodontics, zinc is used as an etching solution to help clean and roughen the surface of teeth. Used as reaction fertilizer in the soil around a granule acidification is generated that improves the utilization of phosphorus applied and available in the rhizosphere. Due to its nitrogen content (present as ammonia), it is good for crops that require these nutrients in its initial phase.
