摘要：

The　phase　relationship　of　the　TbO1.81-Mn3O4-Fe2O3　pseudo-ternary　system　synthesized　at　1200　degrees　C　was　determined　using　X-ray　and　neutron　diffraction　method.　Four　solid　solutions,　Mn3-3xFe3xO4　(0.00　＜=　x　＜=　0.278),　Mn3-3xFe3xO4　(0.291　＜=　x　＜=　0.667),　Mn2-2xFe2xO3　(0.89　＜=　x　＜=　1.00),　and　(Tb1-yMnzFex)　(FewMn1-w)O-3　(1-y　+　x　+　z　＜=　1,　0.00　＜=　w　＜=　1.00)　were　found　along　with　six　two-phase　regions　and　three　three-phase　regions.　The　boundaries　were　determined　by　several　different　methods　such　as　phase　disappearing,　the　Vigard＇s　law,　and　the　lever　rule.　(C)　2012　Elsevier　B.　V.　All　rights　reserved.
