This verified that after adding the Mg2+ ion and Er3+ ion to crystal lattice of CaCO3 , the crystal structure did not change dramatically, but due to the radius of Mg2+¡¢ Er3+ and Ca4+ ions are 0.87Å¡¢0.9Å and 0.69Å .

it has been proved that, the radius of Mg2+¡¢ Er3+ and Ca4+ is so big that the crystal structure had little change with addition of all the three ions to the crystal lattice of CaCO3.
