| Overview | sodium pyroantimonate is a white powder with granular and equiaxed crystals, it does not decompose at 1000 ° C., and can be used as high-grade glass fining agent and decolorizing agent, flame retardant for plastics and textiles, opacifying agent for enamel and ceramics, and opaque coating for foundry paint. |
| trait | sodium pyroantimonate is white or off-white crystalline powder, soluble in hot water, insoluble in cold water, insoluble in ethanol. |
| Use | sodium pyroantimonate is used as a glass fining agent in the production of high-grade glass such as solar glass, and can also be used as a flame retardant synergist for plastics and rubber. mainly used as fining agent for picture tube glass shell, also used as flame retardant for textiles, plastics, building materials, etc. used as analytical reagent |
| preparation method | Firstly, sodium hydroxide and xylene trioxide are fully reacted instead of water, and then ozone is introduced for full oxidation, recrystallization, centrifugation, drying, the invention uses ozone as an oxidant, oxidation effect is good, through the method of microwave removal to obtain sodium pyrooxide, and then through the microwave removal of sodium pyroantimonate crystal water, finally, the pH was adjusted and dried to give neutral sodium antimonate. The crystal water of sodium pyroantimonate can avoid the yellowing of the generated sodium antimonate at high temperature, adjust the sodium antimonate to neutral, and is more suitable for polymer processing as a flame retardant. The invention has the advantages of simple production process, short reaction time, environmental protection in the process, low production cost and gradual reduction, and the prepared sodium pyroantimonate and sodium antimonate have high purity, high whiteness and neutral pH, it can be widely used as flame retardant in the field of plastics. |
