barium dimetaphosphate - Reference Information
| overview | Ba(PO3)2=295.27, white powder. Insoluble in water, slowly soluble in acid. Used in glass, enamel and porcelain industries. |
| a production process of barium metaphosphate | firstly, barium hydroxide is placed in a container, deionized water and activated carbon are added, stirred and heated to fully dissolve it until the specific gravity is 1.05~1.10, let it stand and filter, and the central control iron, copper, nickel, manganese and cobalt are less than 0.0003% to obtain refined barium hydroxide, which is put into another container; stir, add excellent phosphoric acid, adjust to pH value of 9~11, get barium hydrogen phosphate precipitation; add deionized water dilution, get barium hydrogen phosphate mixed slurry; centrifugal spray drying to synthesize barium metaphosphate. The invention solves the technical problems of complex production process, high production cost and unstable product quality in the background technology. The production process is easy to adjust and control, the product has low impurity content and high yield. applicant (patent right): Shanxi Chaoxin Metal Material Co., Ltd.
