Preserved Fulltext
We have been concerned with a method which is applicable in commercial scale. CaHPO4 was produced by precipitating a fraction of P2O5 using calcium carbonate (not any other calcium salt) in order to achieve the precipitation reaction in a pH below the pH of uranium and fluoride precipitation range. Finally we adjusted the pH of the final product and the ratio between Ca and P. Therefore, the final product is not contaminated with uranium.
