| Abstract: | Introduction the degradation of available P2 05 of SSP maked from phosphate rock with high iron and aluminum content. Analysis the degradation of available P2O5. It can improve and prevent the degradation of available P2O5 by increasing phosphate rock degree of fineness and raising the amount of sulfuric acid,with a reasonable source of phosphate rock and reduction of touring temperation. |
