Webthe air reactor). The stable phases at low temperature are hematite and bixbyite, both with the general formula (Fe 1−xMn x)2O3, whereas the spinel phase (Fe 1−xMn x)3O4 is stable at high temperature. There are also two-phase areas in which both forms i.e. bixbyite/hematite and spinel, coexist at intermediate temperatures. WebJoel E. Arem, Ph.D., FGA. Dr. Joel E. Arem has more than 60 years of experience in the world of gems and minerals. After obtaining his Ph.D. in Mineralogy from Harvard University, he has published numerous books that are still among the most widely used references and guidebooks on crystals, gems and minerals in the world.
