PURPOSE:To enable easy synthesis of silver ion conductive solid electrolyte by conducting the reaction of a mixture of silver iodide, silver oxide and tungsten oxide in the molten state with heat. CONSTITUTION:A mixture of silver iodide, silver oxide, and tungsten oxide, or a mixture of silver iodide and silver tungstate are used as a starting substance to synthesize silver ion conductive solid electrolyte. Thus, presynthesis of silver tungstate becomes unnecessary and the synthetic process can be simplified. Further, the solid electrolyte is prepared without use of unnecessary substance for the electrolyte an the costs can be decreased. Further, the mixture of feedstocks is heated in air without use of Pyrex glass tubes for enclosing the mixture and a large amount of product can be produced in no need of oxygen gas or nitrogen gas. Thus, installation costs are reduced. |
