Characteristics: Colorless transparent monoclinic crystal prism system, the relative density of 1.52, in the air easily weathered, easy to lose the five crystal water molecules and the formation of seven water properties (Na2HPO4.7H2O). Soluble in water, insoluble in alcohol. Solution was slightly alkaline reaction (0.1-1N solution PH of about 9.0). Lose crystal water at 100 from anhydrous, 250 when broken down into sodium pyrophosphate.
Uses: used as boiler water softener, fabric, wood and paper fire retardant paper, glaze and coat. For the production of detergents, cleaning agents and the print version of mordant dyeing. In the printing industry for the stability of hydrogen peroxide bleaching agent, artificial silk filler (Enhanced wire strength and flexibility.) Focus is to create sodium phosphate and other phosphate materials, but also MSG, erythromycin, penicillin, streptomycin and sewage treatment products, such as production of training agents. Also used in electroplating, leather industry.
