【正文】 空隙中穿過(guò)，由致 密層與多孔層形成的復(fù)合電解質(zhì)相對(duì)于單一的致密層有著較高的電導(dǎo)率 ，且 βAl2O3復(fù)合電解質(zhì) 的電導(dǎo)率隨著加熱溫度的升高而提高，材料的活化能為 。, the posite layer was added βAl2O3 powder mass of 1% aluminum stearate added in an amount of βAl2O3 powder mass to 1% polyacrylic acid is not added for codeposition, aluminum stearate deposition during sintering, the grain refinement can and form a uniform gap due to the porous layer of sodium ions passing through the gap, the dense layer and the porous layer with respect to a single posite electrolyte , the dense layer can be prepared with a high electrical conductivity is good and a relatively high βAl2O3 posite electrolyte. Through this experiment can be learned, and: βAl2O3 posite conductivity of the electrolyte is heated with the increase of the temperature increase, the activation energy of the material .
