Abstract: The invention 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 invention further relates to ceramic grains obtainable by a method of the invention.
