摘要
The sinter behaviour of (La, Sr)MnO3 has been studied on samples with 0, 15, 30, and 50 at.% Sr prepared by coprecipitation. With increasing strontium content the sinter curves are shifted to higher temperatures. This shift can be explained by a combined effect of the difference in ionic radii between La3+ and Sr2+, and by a decrease of the number of defects that are formed in (La, Sr)MnO3. The sinter behaviour of coprecipitated samples is compared with samples obtained from citrate pyrolysis.
