Novel developments in alpha-SiAlON ceramics
(Trans Tech Publications LTD, 2000)
Densification and stabilization of alpha-sialon ceramics have been investigated by using oxides of large cations (Sr2+, La3+, Ce3+, Nd3+) and their equimolar mixtures with calcium or ytterbium as a principal cation. All ...
The effect of different nucleation temperatures on the grain morphology of alpha-SiAlON ceramics
(Trans Tech Publications LTD, 2003)
Nitrogen rich yttrium-cerium containing multi-cation alpha-SiAlON starting compositions were prepared by gas pressure sintering using conventional alpha-Si3N4 powder. Microstructural characterization of the two stage ...
Effects of different Si3N4 starting powders and sintering conditions on the grain morphology and mechanical properties of alpha-SiAlON ceramics
(Trans Tech Publications LTD, 2002)
Nitrogen rich yttrium-cerium containing multi-cation alpha -SiAlON starting compositions have been prepared by gas pressure sintering using "conventional" alpha -Si3N4 or alpha-beta Si3N4 containing powder. The effect of ...
Improvement of elongated alpha-SiAlON ceramics by variation of the processing conditions and amounts of additives
(Trans Tech Publications LTD, 2002)
Two types of Y-alpha -SiAlON composition, with different amounts of additional liquid phase were densified in a gas pressure sintering furnace using three different sintering cycles. One series of samples was heated up to ...
