Abstract
Perovskites are investigated as potential working materials in new technologies, such as solid ox - ide fuel cells, thermochemical energy storage, and magnetic refrigerators. They are interesting due to their application properties, such as electrical conductivity, ferromagnetic properties, and reducibility. Properties of perovskites can be improved by doping and the formation of structural defects. The aim of this work was to investigate the possibility of preparing Sr-doped lanthanum manganite with the chemical formula La 0.5 Sr 0.5 MnO 3 by coprecipitation procedure, and to analyse the observed phase separation. The material was prepared by procedure in which sources of metal cations (La 3+ , 2+ phase, especially when in tablet form.
期刊介绍：
Kemija u industriji (Chemistry in industry) is monthly journal which is being published already for almost 60 years continually and from very beginning it is a journal of chemists and chemical engineers. It is official journal of Croatian Society of Chemists and Engineers and of Croatian Chemical Society. It is edited by Croatian Society of Chemists and Engineers.
