Abstract
In the present paper, the effects of the mixed powders prepared from solid state reaction method and glycine–nitrate combustion technique on properties of electrolyte, including sintering behaviour, mechanical property and electrical conductivity, were investigated. The results denoted that the relative density, the flexural strength and the electrical conductivity decreased with increasing powder content prepared by the glycine–nitrate combustion technique. The fracture mode also changed from intergranular to transgranular. The thermal shock resistance was also studied. The results denoted that Sr- and Mg doped lanthanum gallate had a weak thermal shock resistance. The phase constitution was conducted by X-ray diffractometry (XRD). The microstructure was observed by means of scanning electron microscopy (SEM) and the electrical conductivity was measured using impedance analyser.
