Abstract

Flash sintering is a method to rapidly densify materials by applying an electric field at elevated temperatures [1]. Besides densification, flash sintering is also a technique for reactive sintering. A number of materials, including Al₂TiO₅, have been synthesized by flash sintering [2]. Utilizing the thermal runaway, ion migration, or defect creation resulting from the flash could allow for the synthesis of novel materials. This work has demonstrated the simplest synthesis, the transformation of one phase into another. When Mn₂O₃ is flash sintered under the appropriate experimental parameters, it transforms into Mn₃O₄ during stage III.
