內容簡介Volume 55,Number 5,2021Preparation of Si3N4 porous ceramics via foam-gelcasting combined catalytic nitridation/Han Lei,Li Xiaojian,Zhang Haijun//Naihuo Cailiao.-2021,55（5）:395Abstract:Si3N4 porous ceramics were fabricated by foam-gelcasting combined catalytic nitridation using high-purity silicon powders as the starting material and Fe（N03）3-9H20 as the catalyst and CTAB as the foaming agent.The effects of the nitriding temperature （1 200,1 250,1 300 and 1 350℃） and the catalyst addition （0,1%,3%and 5%,by mass） on the phase composition,microstructure and physical properties of the Si3N4 porous ceramics were investigated.
