Study of the phase transformation induced by flash sintering in Mn2O3 and the investigation of the role of defects in flash sintering using in-situ Raman spectroscopy
March 10-15, 2019
Flash sintering is a method to rapidly densify materials by applying an electric field at elevated temperatures . Besides densification, flash sintering is also a technique for reactive sintering. A number of materials, including Al2TiO5, have been synthesized by flash sintering . 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.
