Flash sintering (FS) is an energy efficient sintering technique involving electrical Joule heating, which allows very rapid densification (< 60 s) of particulate materials. Since the first …
Despite sintering has a history even longer than human civilization (its discovery dates back at least to 25,000 years ago), in the past decade, new exciting challenges have emerged in …

The large bank of data for ceramics from experiments in flash sintering reveal a surprising characteristic: that the transition to a highly nonlinear rise in electrical conductivity—a …
Electricity is an efficient form of energy, and the growing interest in electricity-assisted manufacturing is motivated by its inherent energy saving and reduced environmental impact …
Mixed powders of Bi2O3 and Fe2O3 are shown to yield single-phase, dense nanostructured polycrystals of BiFeO3 in reaction flash sintering experiments, carried out by applying a field …
In current-rate flash-sintering experiments the current is injected into the specimen from the very start and then increased at a constant rate, while the furnace is held at a constant …
Flash sintering involves very rapid densification of ceramic powder compacts during a thermal runaway induced by an applied voltage and current. The mechanisms of fast …
The present study investigates the impact of point defects and their redistribution on the flash sintering process. Strontium titanate was chosen as a model system for the group of …
