Outline of Final Research Achievements

Novel divalent Sn compounds was synthesized under microwave non-equilibrium reaction field and a synthesis mechanism of divalent Sn compounds was revealed. Two novel divalent Sn compounds was successfully synthesized by microwave irradiation. Microwave rapid heating and unidirectional diffusion of Sn ion from SnO to other oxides are important role to synthesize divalent Sn compounds.
