Optimization of alpha-sialon microstructure by heat treatment
(Trans Tech Publications LTD, 2008)
Nd-doped alpha-SiAlON starting composition (Nd(0.33)Si(9.38)Al(2.62)O(1.62)N(14.38)) was prepared by gas pressure sintering at 1825 degrees C for 3 hrs. In order to explore the effect of post heat treatment on the developments ...
Optimization of ?-sialon microstructure by heat treatment
(2008)
Nd-doped ?-SiAlON starting composition (Nd0.33Si 9.38Al2.62O1.62N14.38) was prepared by gas pressure sintering at 1825°C for 3 hrs. In order to explore the effect of post heat treatment on the developments of elongated ...
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 ...
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 ...
Interactions Between AlN and SiAlON Ceramics
(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 ...
Chemical durability behaviour of bulk glasses in the Er-SiAlON system: Surface characterisation by SEM
(Trans Tech Publications LTD, 2004)
Er-SiAlON glasses were produced by melting appropriate powder mixtures under nitrogen at 1715 degreesC using a cation ratio composition of Er:Si:Al = 3.45:3:2 and with varying nitrogen contents (N= 5 to 22 equivalent %). ...
