Incorporation of the transition metals (Cr and Fe) into beta-SiAlON crystal structure
(Elsevier Sci LTD, 2011)
Outstanding properties for SiAlON ceramics can be obtained by tailoring the microstructure through alpha-SiAlON and beta-SiAlON phase content as well as a type of secondary phases. It is so far well known that while some ...
Analytical transmission electron microscopy observations on the stability of TiCN in electrically conductive alpha-beta SiAlON/TiCN composites
(Elsevier Sci LTD, 2014)
Coating of alpha-beta SiAlON granules with TiCN powder led to a continuous 3D electrically conductive network formation. Here, the stability of TiCN grains following gas pressure sintering (GPS) and its effect on the ...
Towards atomic scale engineering of rare-earth-doped SiAlON ceramics through aberration-corrected scanning transmission electron microscopy
(Pergamon-Elsevier Science LTD, 2011)
Direct visualization of rare earths in alpha- and beta-SiAlON unit-cells is performed through Z-contrast imaging technique in an aberration-corrected scanning transmission electron microscope. The preferential occupation ...
Effect of sintering conditions and heat treatment on the properties, microstructure and machining performance of alpha-beta-SiAlON ceramics
(Elsevier Sci LTD, 2012)
The properties of SiAlON ceramics are strongly affected by the composition and structure of the intergranular phase, which are controlled by dopants, sintering conditions and starting silicon nitride (Si3N4) powder ...
Identification of Ti incorporation into beta-SiAlON crystal structure through transmission electron microscopy techniques
(Elsevier Sci LTD, 2012)
In this paper, we report the transmission electron microscopy (TEM) observations on the incorporation of Ti transition metal element into beta-SiAlON crystal structure in a bulk beta-SiAlON-TiN composite material. Considering ...
A novel approach on the synthesis of beta-SiAlON:Eu2+ phosphors from kaolin through carbothermal reduction and nitridation (CRN) route
(Taylor & Francis LTD, 2014)
Doping beta-SiAlON crystal structure with rare earths leads to a superior tuneable luminescence properties for light emitting diodes (LEDs). However, the widely used conventional methods require high purity starting powders ...
