Experimental Study of Ba₇Fe₄O₁₃, Ba₃Fe₂O₆, Ba₂Fe₂O₅, BaFe₂O₄Barium Ferrites

Abstract:

This paper presents the results of synthesis of BaO-Fe₂O₃ system compounds. The powder X-ray diffraction patterns are presented. The patterns of Ba₃Fe₂O₆, Ba₂Fe₂O₅ and BaFe₂O₄ coincide with literature data. The experimental cell parameters were calculated. The study results of nature and the melting temperatures of Ba₃Fe₂O₆, Ba₇Fe₄O₁₃, Ba₂Fe₂O₅, BaFe₂O₄ are described. The compounds have congruent melting character. The melting temperatures of listed compounds are 1325, 1320, 1365, 1405 °C (1598, 1593, 1638, 1678 K), respectively.
