| Abstract: | Effects of the amount of H2SO4,Na2SiO3.9H2O and Na2CO3,andreaction temparature on the content of fluorine in feed grade calcium hydrophosphate were studied.The optimum process conditions were determined.Feed grade hydrophosphate with a quality of HG 2636-94 standard was produced by one step defluorination.The yield of phosphrous reached more than 96% from 50％～60％ of traditional two step defluorination. |
