The driving force for ??ß transformation in rare earth ? sialon ceramics
(1997)In-situ ??ß sialon transformation in rare earth sialon systems, which occurs when dense ?- and ?/ß-sialon samples are heat-treated at temperatures in the range 1300-1600°C was first observed five years ago, and has generated ... -
The effect of processing conditions, amount of additives and composition on the microstructures and mechanical properties of alpha-SiAlON ceramics
(Elsevier Sci LTD, 2002)A series of samples with yttrium alpha -SiAlON compositions and different amounts of additive has been fabricated from alpha -Si3N4, AIN, Al2O3 and Y2O3 starting powders, using gas pressure sintering and three different ... -
Investigation of the phase composition and stability of the alpha-SiAlONs by the Rietveld method
(Elsevier Sci LTD, 2002)Different compositions of Y- and Nd-alpha-SiAlONs were sintered at 1825 degreesC and analysed by the XRD method. The Rietveld technique was used for characterisation of the diffraction pattern and the x value of alpha-SiAlON, ...
