摘要: Both of the previously proposed Pbnm and P6522 ordered structures for vaterite are found to be unstable transition states using first-principles methods. Five stable located, lowest energy one being P3221 symmetry. Since interconversion between these requires only thermal energy, this provides an additional source disorder within structure.
