The Front Cover shows a schematic on the relevance of the thermal cycle for the FLASH sintering of lead‐free piezoelectric K0.5Na0.5NbO3 (KNN). The use of an Isothermal Condition (I.C.) prior to the FLASH event allows neck formation and particle surface smoothening. Therefore, a more uniform current distribution upon FLASH is achieved, as shown by the Finite Element Modelling simulations, and consequent higher and more uniform densification (ρ) is promoted.
