  • Publication number: 20170157667
    Abstract: The disclosure herein relates to a method for preparing ceramic grains comprising: making a slurry comprising inorganic particles and a gelling agent; making droplets of the slurry; introducing the droplets in a liquid gelling-reaction medium wherein the droplets are gellified; deforming the droplets before, during or after gellification; drying the gellified deformed droplets, thereby obtaining dried grains and sintering the dried grains, thereby obtaining the ceramic grains. The disclosure herein further relates to ceramic grains obtainable by a disclosed method.
