Abstract

In order to synthesize various Perovskite ABO3 type compounds and their solid solutions, we have applied a novel "melt synthesis technique" rather than conventional solid state reaction techniques. In the melt synthesis, the mixture of oxides or their precursors is melted in a short period of time (1-60 sec) by a strong light radiation in an arc imaging furnace. A spherical molten sample where multiple cations were mixed homogeneously was directly solidified on a copper hearth with a rapid cooling of 10 2K/sec. LaAlO3, GdScO3, ATiO3(A = Ba, Sr, Ca and La) and the solid solutions among them, (A1-xA' x)(B1-yB'y)O3, were synthesized in this technique. Madelung potentials was calculated by MADEL, and discussed about lattice energy of these components.
