Abstract
This paper presents the results of synthesis of BaO-Fe 2 O 3 system compounds. The powder X-ray diffraction patterns are presented. The patterns of Ba 3 Fe 2 O 6 , Ba 2 Fe 2 O 5 and BaFe 2 O 4 coincide with literature data. The experimental cell parameters were calculated. The study results of nature and the melting temperatures of Ba 3 Fe 2 O 6 , Ba 7 Fe 4 O 13 , Ba 2 Fe 2 O 5 , BaFe 2 O 4 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.
