Probing the densification mechanisms during flash sintering of ZnO
Using ZnO as a model system, the densification mechanisms of flash sintering are investigated. Controlled experiments via limiting the maximum current or the effective ramp rate suggest that both the maximum specimen temperature and the high heating rate (on the order of 200 C/s) are essential for the rapid densification during the flash sintering. Moreover, benchmarking rapid thermal annealing...
متن کامل7 Visible Light and UV Radiation
The sun is the most important source of visible and ultraviolet (UV) radiation. Even though the distance from the sun to the Earth is large – about 150×10 km – the fluence rate of solar radiation on Earth, the solar constant, is about 1 360 W/m 2 . Approximately 40% of this radiation is reflected back into space. The remaining 60% is the driving force of all life on Earth. A number of pigments ...
متن کامل8YSZ sintering by flash sintering method and evaluation of process parameters
Flash sintering as a new sintering method for sintering of ceramic materials has been studied and effect of various parameter such as flash current density, time of flash and contact paste on properties of flash sintered 8YSZ samples has been investigated. Results showed it is possible to achieve high density in shorter time and lower temperature than conventional sintering methods. Samples cou...
متن کاملThermal runaway, flash sintering and asymmetrical microstructural development of ZnO and ZnO–Bi2O3 under direct currents
DC flash sintering of both pure and 0.5 mol.% Bi2O3-doped ZnO at a relatively high activating field of 300 V/cm has been investigated. It is demonstrated that even high-purity ZnO single crystals can “flash” at 870 C. In comparison, flash sintering occurs at a substantially lower onset temperature of 550 C in ZnO powder specimens, indicating the important roles of surfaces and/or grain boundari...
متن کاملUltrafast-Contactless Flash Sintering using Plasma Electrodes
This paper presents a novel derivative of flash sintering, in which contactless flash sintering (CFS) is achieved using plasma electrodes. In this setup, electrical contact with the sample to be sintered is made by two arc plasma electrodes, one on either side, allowing current to pass through the sample. This opens up the possibility of continuous throughput flash sintering. Preheating, a usua...
