摘要

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, (A_1-xA' _x)(B_1-yB'_y)O₃, were synthesized in this technique. Madelung potentials was calculated by MADEL, and discussed about lattice energy of these components.
