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 ...
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 ...
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 ...
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 ...
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 ...
The effect of the wet-milling process on sintering temperature and the amount of additive of SiAlON ceramics
(Elsevier Sci LTD, 2010)
In this study, nano-sized SiAlON powders were produced by wet milling at elevated speeds as a top-to-bottom process. Before the milling process, different milling times and mediums were performed for the determination of ...
Improvement in the Oxidation Resistance of beta-SiAlON Ceramics Produced from Mechanically Milled Powders
(Trans Tech Publications LTD, 2012)
In the present study the oxidation behavior of beta-SiAlON ceramics, which were produced from conventional and high energy mechanical milled powders, was investigated. High energy mechanically milled powders have lower ...
A comparison of sintering techniques using different particle sized beta-SiAlON powders
(Elsevier Sci LTD, 2012)
In the present study sintering behavior and mechanical properties of beta-SiAlON ceramics were investigated using different sintering techniques (gas pressured sintering (GPS), pressureless sintering and spark plasma ...
Cytocompatibility property evaluation of gas pressure sintered SiAlON-SiC composites with L929 fibroblast cells and Saos-2 osteoblast-like cells
(Elsevier Science BV, 2012)
Although the oxide ceramics have widely been investigated for their biocompatibility, non-oxide ceramics, such as SiAlON and SiC are yet to be explored in detail. Lack of understanding of the biocompatibility restricts the ...
