Interactions Between AlN and SiAlON Ceramics
Kalemtaş, Ayşe; Acikbas, N. Çalış; Kara, Ferhat; Mandal, Hasan; Krnel, K.; Kosmac, T. (Trans Tech Publications LTD, 2009)In the present study, interactions between AlN and SiAlON laminated couples were investigated after gas pressure (GPS) and spark plasma sintering (SPS) by scanning electron microscopy (SEM) and energy dispersive x-ray ... -
Investigation of parameters affecting formation of mullite from kaolin
Aksel, Cemail; Kalemtaş, Ayşe (Trans Tech Publications LTD, 2004)This study aims to improve the understanding of formation of mullite from kaolin at low process temperature using different sintering regimes. The optimum parameters affecting mullite formation from kaolin such as sintering ... -
Joining of SiAlON ceramics to pyrex glass
Kalemtaş, Ayşe; Kara, Alpagut; Kara, Ferhat; Mandal, Hasan; Aktug, B (Belgian Ceramic Society, 2004)In the present study, pressureless joining of gas pressure sintered (alpha-beta)-SiAlON ceramics to pyrex glass was investigated. Preoxidized SiAlON ceramics were used to enhance wettability and provide chemical compatibility ... -
Mechanical characterization of highly porous beta-Si3N4 ceramics fabricated via partial sintering & starch addition
Kalemtaş, Ayşe; TopAteş, Gülsüm; özcoban, Hüseyin; Mandal, Hasan; Kara, Ferhat; Janssen, Rolf (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- ... -
Pressureless Melt Infiltrated Non-Oxide Ceramic-Metal Composites
Kalemtaş, Ayşe; Arslan, Gökhan; Kara, Ferhat (Trans Tech Publications LTD, 2009)In the present study highly dense (open porosity < 1 %), light-weight (d <= 2.85 g/cm(3)) and Al(4)C(3)-free non-oxide ceramic-metal composites were produced at comparatively low temperatures (<= 1250 degrees C) by pressurless ...
