Cationic impurities like Na+, Mg2+, Zn2+, Y3+, La3+, Nd3+, Gd3+, Dy3+ have been doped in pure aragonite and their effect on the kinetics and energetics of its transformation to calcite is studied.
On a dopé de l'aragonite pure avec des impuretés cationiques comme Na+, Mg2+, Zn2+, Y3+, La3+, Nd3+, Gd3+, Dy3 + et on a étudié leur effet sur la cinétique et les profils énergétiques de sa transformation en calcite.
