Abstract: Anew sodium zincosilicate single crystal Na1.0Zn1.62Si1.38O4.84·0.6H2O with size of 0.3mm×0.3mm×0.3 mm was prepared by hydrothermal synthesis method. Powder X-ray diffraction analysis result shows that this compound is a new phase.The compound is stable up to 500℃. The results of ACimpedance measurement shows that its ionic conductivity at 450℃ is 2×10-4S·cm-1 and the activation energy for ionic conduction is 79.64 KJ/mol.
