      abstract     = {Field-assisted processing methods, such as spark plasma
                      sintering and flash sintering, have considerably expanded
                      the toolbox of ceramic engineering. Depending on the
                      conditions, substantial electric currents may flow through
                      the material resulting in fast heating rates due to Joule
                      heating. Here, we focus on nonthermal effects induced by
                      electric fields during processing of fluorite- and
                      perovskite-based ceramics. The fundamentals of how a field
                      can directly modify defect formation and migration in
                      crystals are discussed. In addition, the interplay of ion
                      transport and electrical conductivity is considered, this
                      interplay being crucial to understanding nonthermal effects
                      caused by electric fields (as in memristive switching).
                      Electrochemical reactions leading to new phases or reduction
                      are also described, as are densification rates and sintering
                      parameters that are significantly affected even though the
                      sample temperature is held constant. Finally, as
                      grain-boundary properties and segregation are changed by ion
                      transport, we describe how both retardation and acceleration
                      of grain growth can be achieved including graded
                      microstructures.},
