Ammonia Sensing Characteristics of Solid Electrolytes Based on Ammonium Hydrogermanate

摘要

The solid electrolyte based on ammoniumhydrogermanate in which the germanium site was partiallysubstituted for phosphor was prepared by a hydrothermal methodand the ammonia gas sensing characteristics of the electrolytewere investigated by fabrication an ammonia gas concentrationcell. The electromotive force output of the response changedimmediately after the NH3 gas variation and a reproducibleresponse which obeyed the Nernst equation was exactly observed.
