低配位状態を利用した微粒子固体表面反応の機構と応用

抄録

Theoretical background of bridging bond formation of dissimilar metal atoms mediated by an oxygen atom is given for the system Ca(OH)₂-SiO₂. Physicochemical significance of low coordination state is emphasized in conjunction with higher reaction probability. A solid state addition reaction at room temperature is shown to be well possible when mechanical stress is applied to promote materials transfer via a mechanical diffusion. Application of such a soft-mechanochemical process is given for complex perovskite oxides. Associated ligand field distortion is also used for solid state synthesis of Fe (II) octahedral comlexes, e.g., Fe (II) (phen)₂Cl₂, where phen denotes 1, 10-phenanthroline.
