Electromagnetic/Electric Fields in Ceramics Synthesis and Processing: Far from Equilibrium Effects

Date: January 20, 2021

Time: 12:00PM - 01:30PM

You must be registered to participate!

Electric and electromagnetic fields can promote far-from-equilibrium chemical reactions, phase transformations, and microstructural evolution. From an industrial standpoint, processing advanced materials using externally applied fields can have a smaller energy footprint compared to conventional methods, and as such will have a profound impact on society. The January, 2021 issue of MRS Bulletin visits some of the scientific questions that remain about the fundamental mechanisms underlying interactions of external fields with matter. More opportunities can present themselves as we expand our studies to various material systems.

This webinar will present three talks with authors from the MRS Bulletin issue. An interactive Q&A will be held with each of the speakers following their talks.

Talk presentations:

  • Flash sintering: A new frontier in defect physics and materials science
    Rishi Raj, University of Colorado
    Talk begins at 5:24

  • From Flash Sintering to Electric Field Effects on Grain Growth: Mechanisms Learnt from Studies of ZnO
    Jian Luo, University of California, San Diego
    Talk begins at 32:25
     
  • Modeling of flash sintering of ionic ceramics
    R. Edwin Garcia, Purdue University
    Talk begins at 1:04:28
