Function: P2O5 is mainly used as industry raw materials and reagent. Widely usedin pharmaceuticals, coating additive, dyeing auxiliary, antistat, coupling agent of organic titanate, phosphorus oxychloride, etc. Also used for producing high purity phosphoric acid, drying agent for gas and liquid, dehydrant for organic synthesis, and for the manufacturing of organophosphorus ester.
Health Hazard:Non-ignitable, reacting vigorously and omitting heating or burning while meeting waterand organic matters such as wood, cotton or grass. And omitting heat and smoke when soluble in water. Slightly corrosive to metals when affected with damp. Powder and fumes in the air are irritating to eyes and the respiratory tract. Particles in contactwith eye react vigorously and even a small amount may cause permanent burns. Contact with the skin will cause severe burns. Ingestion will damage the gastrointestinaltract. Corrosive to skin, mucous membranes and eyes.
