Conventional sintering of complex oxides is often fraught with undesirable phase transformations and, sometimes, loss of low melting and volatile constituents. Furthermore the synthesis of powders of these complex oxides also poses a challenge again for similar reasons. We show that reactive flash sintering where the powders of simple constituents, for example bismuth oxide and ferric oxide, can simultaneously react and sinter to form phase pure bismuth ferrite with highly insulating properties, which are elusive in conventionally sintered experiments. Results on other systems of technological significance will also be presented.
