Research Highlights

  • Finding of ceramics superplasticity for the first time in the world.(1985.07)
  • Mechanical principles behind sintering in micro- and macro scales


  • March 2017
    We developed a method to estimate thermodynamic driving force of sintering from the analysis of X-ray microtomography (Journal of the American Ceramic Society 2017)
  • June 2016
    We developed a micro-mechanical test method using micro-cantilever beam specimens to determine the very early part of resistance curve (Scientific Reports2015, Nikkei Sangyo Shimbun, Kagaku Kogyo Nippou)
