| Abstract Scope |
The science of the flash method pioneered in 2010 in the context of sintering of ceramics, has recently shown unusual results that apply to both metals and ceramics: (i) generation of colossal concentration of defects in the solid state, of up to 25 mol%, (ii) rates of diffusion accelerated by up to eight orders of magnitude, (iii) generation of a solid state plasma, and (iv) electroluminescence. It applications has broadened far beyond sintering into, for example, ultra-rate reactions in solid state chemistry, such as the conversion of ZnS into ZnO in a few seconds at low furnace temperatures. Refractory metals have been sintered in a few seconds without a furnace by the injection of electrical current. Other examples would be described, time permitting. This talk will describe these scientific and technological aspects of flash. |
