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 ...
Effect of SiC addition on the thermal diffusivity of SiAlON ceramics
(Elsevier Sci LTD, 2017)
Despite the fact that thermal conductivity is a crucial parameter for SiAlON ceramics with respect to their suitability in various applications, including high-temperature structural components, wear parts, and cutting ...
An alternative composite approach to tailor the thermoelectric performance in SiAlON and SiC
(Elsevier Sci LTD, 2017)
The thermoelectric properties of SiAlON and SiC based composites prepared by adding TiCN (5 and 10 vol.%) as a particulate or as a segregated three-dimensional network were investigated. Although the volume fraction of the ...
Effect of heat treatment on green machinability of SiAlON compacts
(Elsevier Science Sa, 2014)
SiAlON based ceramics are promising materials for wear applications such as wire extrusion dies, pipe bending rollers, etc. due to their outstanding mechanical properties both at high and low temperatures. To be able to ...
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 ...
Tailoring the properties of spark plasma sintered SiAlON containing graphene nanoplatelets by using different exfoliation and size reduction techniques: Anisotropic mechanical and thermal properties
(Elsevier Sci LTD, 2018)
SiAlON ceramics are intensively used in different areas but still there is a need to improve the mechanical and thermal properties as well as ease of machinability and reduce the weight. In this study, the effect of graphene ...
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 ...
