Název v původním jazyce

Synthesis of doped lanthanum ferrite perovskites

Popis výsledku v původním jazyce

La1-xSrxFe1-yTiyO3-d where x = 0.8 and y is varied from 0.2 to 0.8 perovskite systems were prepared via several methods. Both novel methods spray pyrolysis and glycine/nitrate combustion synthesis were compared with conventional solid state reaction withmechanical activation. The "wet chemical routes"of preparation proceeded from aqueous solution of nitrates of appropriate metals. As precursors of conventional route the homogenous mixtures of appropriate metal oxides were used. The properties of prepared ceramic powders were studied by XRD, chemical analysis, SEM, particle size determination, BET method, SEM. The comparison of products properties of prepared ceramic powders shows that the novel methods lead to improved final properties then the conventional technique. Nanostructured phase pure doped lanthanum ferrites with high specific surface area were prepared by spray pyrolysis.
