Ultrafast-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...
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 کاملContinuous Flash
To take a picture of scene, we acquire multiple images under different levels of flash intensity (possibly just " flash on " and " flash off "), and let the user subsequently adjust the flash level continuously by interpolating among the stored images. Camera motion is corrected using image registration techniques robust to intensity differences. Flash adjustment occurs either immediately on th...
متن کاملOn the Mechanism of Microwave Flash Sintering of Ceramics
The results of a study of ultra-rapid (flash) sintering of oxide ceramic materials under microwave heating with high absorbed power per unit volume of material (10-500 W/cm³) are presented. Ceramic samples of various compositions-Al₂O₃; Y₂O₃; MgAl₂O₄; and Yb(LaO)₂O₃-were sintered using a 24 GHz gyrotron system to a density above 0.98-0.99 of the theoretical value in 0.5-5 min without isothermal...
متن کاملProbing 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...
