Mechanical characterization of highly porous beta-Si3N4 ceramics fabricated via partial sintering & starch addition
(Elsevier Sci Ltd, 2013)In this study, porous beta-Si3N4 ceramics containing limited amount of Sm2O3 and CaO as sintering aids were produced by addition of potato starch (10 and 20 vol.%) and partial sintering. Two different Si3N4 powders, alpha- ...
