Trisodium phosphate also known as sodium phosphate, commercially known as sodium phosphate, performance characteristics: colorless acicular Crystal hexagonal crystal system. Soluble in water, insoluble in organic solvents, relative density1.62(20℃) ; melting point 73.3-76.7℃(decomposition); in drier air, loses 12 crystal water on the 100 ℃ and produce anhydrous (Na3PO4). Aqueous alkaline skin has some erosion. In the industrial grade is mainly used in water softening agent, boiler cleaning and detergents, non-metallic and fabric mercerization additives; food grade as quality improver, emulsifier, nutritional supplements, pasta of, etc.
