A comparative study of SiAlON ceramics
(Elsevier Sci LTD, 2012)Two different varieties of Si3N4 powders were used to prepare SiAlON ceramics. 100% beta-Si3N4 was used from refractory grade powders (B1) and another purer 98% alpha-Si3N4 (50A) powder was used to prepare the SiAlON ... -
Microstructure-Mechanical Properties-Wear Resistance Relationship of SiAlON Ceramics
(Springer, 2009)In designing wear-resistant ceramics, it is important to understand the influence of the microstructure and material properties on friction and wear behavior. In addressing such issues, a series of fretting-wear tests was ... -
Influence of SiC addition on tribological properties of SiAlON
(Elsevier Sci LTD, 2011)The tribological properties of gas pressure sintered SiAlON and its composite with 18 wt% silicon carbide (SiC) against two different mating materials, i.e., alumina and SiAlON are evaluated. SiAlON and SiAlON-18%SiC ... -
The effect of z value on intergranular phase crystallization of alpha(1)/beta(1)-SiAlON-TiN composites
(Elsevier Sci LTD, 2017)Relationship between z value and intergranular phase (IGP) chemistry has not been completely developed to date for SiAlON based materials. In this study, the effect of z value of beta(1)-SiAlON on crystallization and ... -
Influence of beta-Si3N4 particle size and heat treatment on microstructural evolution of alpha:beta-SiAlON ceramics
(Elsevier Sci LTD, 2011)In the present study, we report the effects of starting beta-Si3N4 particle sizes and post-sintering heat treatment on microstructure evolution and mechanical properties of prepared alpha-beta SiAlON ceramics. Three different ... -
An investigation of pottery production technology for the West Slope wares from Dorylaion (Eskisehir/Turkey)
(Soc Espanola Ceramica Vidrio, 2013)Researches in the field of pottery production technology in ancient times, done in different settlements during the same period, may contribute to know relationships established within the different cultural communities. ... -
Use of rhyolite as flux in porcelain tile production
(Techna Srl, 2009)The use of rhyolite from a local source as an alternative fluxing agent in a commercial porcelain stoneware formulation was investigated. The experimental work was achieved in two parts: in the first part, standard tests ... -
Effects of Alumina and White Fused Alumina Addition on Transparent Wall and Floor Tile Glazes
(Polish Acad Sciences Inst Physics, 2015)In tile manufacturing, alpha-Al2O3 is the main type of alumina used in ceramic body and glaze formulations. This raw material acts as an pacifier in porcelain tile bodies and as a matting agent in glazes. White fused alumina ... -
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 ... -
Re-use of mud from process waste water purification plant in ceramic tile production
(Techna Srl, 2010)Turkey is the fifth biggest ceramic tile exporter of the world. Considering the expectation that the Turkish tile sector continues to expand, further studies both on the improvement and the development of the tile formulations ... -
Cost Effective Slurry Preparation in Porcelain Tile Production
(Goller Verlag GMBH, 2009)During ceramic tile production (wall, floor and porcelain stoneware), wet milling process for the preparation of ceramic slurries is widely used. The currently preferred wet grinding machines are discontinuous and/or ... -
Processing-structure-property relationship in rigid polyurethane foams
(Wiley, 2017)Rigid polyurethane (PU) foam is used as a thermal insulating and supporting material in domestic refrigerator/freezers and it is produced by reaction injection molding (RIM) process. There is a need to improve the thermal ... -
Evaluating vibration assisted vacuum infusion processing of hexagonal boron nitride sheet modified carbon fabric/epoxy composites in terms of interlaminar shear strength and void content
(Elsevier Sci LTD, 2016)The results of an investigation of the effect of voids on the interlaminar shear strength (ILSS) of carbon fabric/epoxy composites consolidated from fabric preforms containing hexagonal boron nitride sheets (h-BNSs) were ... -
Thermal transport properties of MoS2 and MoSe2 monolayers
(IOP Publishing LTD, 2016)The isolation of single- to few-layer transition metal dichalcogenides opens new directions in the application of two-dimensional materials to nanoelectronics. The characterization of thermal transport in these new ... -
Spinel nitrides transparent ceramics
(Elsevier Sci LTD, 2015)Aluminum oxy-nitride (AlON), a solid solution in the binary phase diagram of Al2O3-AlN, is a relatively new spinel type material. In the present study, the optimum sintering agent and sintering conditions of AlON were ... -
