Some essential trace elements were reported to be involved in the normal bone metabolism. Nowadays rare earth elements are widely used in many fields and more and more rare earth elements enter the environment and food chains They are enriched in bone and difficult to be excreted. Because the similarity between rare earth ions (Ln3+) and Ca2+, they will intervene and regulate bone formation and remodeling.

At experimental equilibrium volume, the total energy of CaTiO〓 increased with the displacement of Ti along [001] direction and the lowest energy point is always at zero displacement of Ti. However, with a 10% volume expansion, the displacement of Ti along [001] direction results in a shallow, but well-defined double energy well and ferroelectricity appears.
