Abstract
Samples of cerium dioxide doped with calcium (3.5 x 10(-3)-3.3 at. %), praseodymium (1.1 x 10(-3)-1.5%), phosphorus (4.6 x 10(-3)-0.45%), an d fluorine (7.5 x 10(-2)-0.75%) have been synthesized. Rate of samples dissolution in sulfuric acid solutions of bivalent iron as a function of atomic fraction of impurity passes through a maximum. Dissolution rate does not correlate with the surface area of the sample.
