SODIUM SULFATE DOPED WITH SODIUM VANADATE AND RARE EARTH SULFATE AS A SOLID ELECTROLYTE FOR A SULFUR DIOXIDE GAS DETECTOR.

Article abstract of DOI:10.1246/bcsj.57.687

Sodium sulfate doped with NaVO//3 and Ln//2(SO//4)//3 (Ln EQUVLNT Eu, Pr, and Y) show higher electrical conductivity for Na** plus ions and maintains a high temperature phase, Na//2SO//4-I, without showing phase transformation. The electromotive force (EMF) using solid solutions, Na//2SO//4-NaVO//3-Ln//2(SO//4)//3 (Ln equals Pr and Y), as solid electrolytes exhibits good agreement with the calculated value, the temperature as low as 673 K which is approximately 300 K lower than pure sodium sulfate can be.
