Powders of four elemental oxides transformed and sintered by reactive flash

Conference Dates

March 10-15, 2019


The cubic phase of a complex oxide of Li, alumina doped lithium lanthanum zirconate, is fraught with issues related to the loss of lithium and unwelcome phase transformations [1]–[3]. Here we show that the cubic phase of this complex oxide can be made by reactive flash sintering with elemental oxides of Li, La, Zr and Al. Transformation and sintering occur at a furnace temperature lower than 700°C in ambient atmosphere. The possibility of discovering new, high-conductivity solid-state electrolytes of lithium through chemistry is greatly enhanced by the viability of the reactive flash sintering process.
