T. Takeuchi et al., EFFECT OF CONTENT OF BATIO3, SURFACE CUBIC LAYER ON THE IONIC-CONDUCTIVITY ENHANCEMENT IN COMPOSITE SOLID ELECTROLYTES, Solid state ionics, 79, 1995, pp. 325-330
The effect of the content of BaTiO3 surface cubic layer on the ionic c
onductivity enhancement of Na4Zr2Si3O12 has been investigated. The cub
ic content increases with increasing applied stress prior to the firin
g and also with increasing of the cooling rate during the processing o
f BaTiO3. The conductivity enhancement depends on the cubic content, a
nd the extrinsic factors to control the enhancement are discussed.
