Production of alpha-beta SiAlON-TiN/TiCN composites by gas pressure sintering
(Belgian Ceramic Society, 2004)
Due to the favorable properties possessed by novel alpha-beta SiAlONs, they are attractive materials for cutting tool applications. Such applications require materials with high hardness, high fracture toughness and high ...
Textured ?-SiAlON ceramics via templated grain growth
(2007)
In this study, textured ?-SiAlON ceramic was produced by templated grain growth process. In order to enhance the alignment of the seeds, gated tape casting arrangement was utilized. Y-Ce codoped seeds were synthesized to ...
Role of alpha-SiAlON nuclei addition on the rod-like y-sm alpha-SiAlON formations
(Trans Tech Publications LTD, 2007)
In this study, effect of seed addition on the microstructural development of Y-Sm alpha-SiAION system has been investigated. Besides using pre-produced rod-like alpha-SiAION seeds, growth in the glassy phase and harvested ...

Joining of SiAlON ceramics to pyrex glass
(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 ...
Effect of different nucleation temperatures on the microstructural development of alpha-SiAlON ceramics
(Trans Tech Publications LTD, 2004)
alpha-SiAlON ceramics with elongated grains were previously observed in different studies. Sintering conditions are known to have a significant role on the microstructural development. By the nucleation treatment application ...
Utilization of a phosphate ester as a dispersant for SiAlON based ceramics
(Trans Tech Publications LTD, 2007)
Aqueous dispersions of SiAION forming powders (Si3N4, AIN and Y2O3) were obtained. Dispersibility of powders was found to be improved by addition of sodium tripolyphosphate. Stable aqueous suspensions of SiAION forming ...
Influence of type of cations on intergranular phase crystallisation of SiAlON ceramics
(Trans Tech Publications LTD, 2007)
25 alpha:75 beta SiAION composition was designed with different cations and at different molar ratios. Effect of the type of cations both on the composition and the type of intergranular phase investigated after gas pressure ...
Pressing behaviour of spray dried alumina-zirconia granules
(Trans Tech Publications LTD, 2004)
In this study, spray drying of alumina-zirconia slurries on a pilot scale, and their pressing behaviour were investigated. Slurries were prepared at 50 wt-% solid loading. An acrylic polymer emulsion, polyethylene glycol, ...
Mg+2 and Ce+3 doped ?-SiAlON ceramics
(2004)
In the present work, stabilization of MgO and CeO2 in ?-SiAlON structure is studied. Mg and CeO2 were used in 50:50 molar ratios as additives. The mixture was sintered at 1830°C for 1 hour in gas pressure sintering furnace ...
