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 ...

Densificaron of Sr-Mg doped SiAlONs with GPS and SPS
(2007)
At temperature above 1200°C, the thermal stability of ?-SiAlON phases has been debated since 1992; however, it has been discussed if any ?-SiAlON phase can be formed in Ce, La, Eu and Sr-doped SiAlON systems. In our previous ...
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 ...
Production of coloured zircon pigments from zircon
(Elsevier Sci LTD, 2007)
Zircon (ZrSiO4) pigments are commonly used in the ceramic industry for glazes due to their high chemical stability and superior resistance to the dissolution during firing in glazes. These pigments are made by calcining a ...

(2007)
In this study, effect of seed addition on the microstructural development of Y-Sm ?-SiAlON system has been investigated. Besides using pre-produced rod-like ?-SiAlON seeds, growth in the glassy phase and harvested by ...
Structural characterisation of Er-Si-Al-O-N glasses by Raman spectroscopy
(Elsevier Sci LTD, 2007)
Er-Si-Al-O-N glasses have been prepared with cation ratio Er:Si:AI=3.45:3:2 containing various amounts of nitrogen (N=O, 5, 8, 15 and 22equiv.%). Glass properties such as microhardness, glass transition temperature and ...
Composition of products obtained via fast pyrolysis of olive-oil residue: Effect of pyrolysis temperature
(Elsevier Science BV, 2007)
As an essential thermochemical process, pyrolysis is mainly dependent on temperature. Temperature affects mostly product distribution and composition. In this study, compositional analysis of the products obtained by thermal ...
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 ...
