| Abstract: | Thermal expansion, electrical conductivity and transference numbers of the Laln0,9Mg0,1O2,95 solid solution having perovskite-type structure with a monoclinic distortion, were studied. Thermal expansion coefficient was calculated from the dilatometric results to be (6,03±0,08)x10-6 K-1. The ceramics possesses mixed ionic-electronic conductivity with oxygen ion transference numbers to be 0,6-0,7 at temperatures of 1123-1223 K. The activation energy for electrical conductivity is 110±1 kJ/mol in the temperature range from 730 to 1210 K. The p-type electronic conductivity of Laln0,9Mg0,1O3-d decreases with reducing oxygen partial pressure, which permits to use the ceramics as gas sensor material. |
