Flame‐assisted flash sintering: A noncontact method to flash sinter coatings on conductive substrates

8YSZ 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...

Microwave flash sintering of inkjet-printed silver tracks on polymer substrates.

Within the last few decades inkjet printing has grown into a mature noncontact patterning method, since it can produce large-area patterns with high resolution at relatively high speeds while using only small amounts of functional materials. The main fields of interest where inkjet printing can be applied include the manufacturing of radiofrequency identification (RFID) tags, organic thin-film ...

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...

On 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...
