The characterization and the utilization of the waste clays from Gumuskoy silver mine in brick industry
(Trans Tech Publications LTD, 2004)In this study, the main characteristics and technological properties of the waste clays from silver deposit located in the northern part of Kutahya (mid-south of Turkey) are presented. The clays were characterized by X-ray ... -
The utilization of waste clay from coal basin in the wall tile body formulation
(Trans Tech Publications LTD, 2004)In this study, the waste clays extracted from coal basin were used as a wall tile ingredient instead of the clay materials of the standardized biscuit formulation of the wall tile. XRD data show that waste clay contains ... -
Fixed-bed catalytic pyrolysis of cotton-seed cake: Effects of pyrolysis temperature, natural zeolite content and sweeping gas flow rate
(Elsevier Sci LTD, 2006)Catalyzed pyrolysis of cotton-seed cake was studied under different experimental conditions. Variables investigated were pyrolysis temperature, zeolite content and sweeping gas flow rate. Experiments were carried out ... -
Evaluation of a natural stone with fluxing capability in stoneware glazes
(Trans Tech Publications LTD, 2004)New glaze systems have been continuously developed in order to supply certain advantages to ceramic bodies such as resistance against external thermal and mechanical forces and an aesthetic appearance as well as hygiene. ... -
Utilisation of a natural stone with fluxing ability in floor tile body as a Na-feldspar replacement
(Trans Tech Publications LTD, 2004)In 1960's the floor tile production of Turkey was started with a large use of K-feldspar as a fluxing agent. However, due to its limited deposits companies begun to employ Na-feldspar instead. At present, considerable level ... -
Effects of the red mud based pigment addition on the physical and micro-structural properties of porcelain tiles
(Trans Tech Publications LTD, 2004)In the production of conventional porcelain tiles colouring agents, being either in the form of pure oxides or pigments, are commonly and widely used at considerably high amounts to increase the attraction impact of final ... -
Producing cordierite from local magnesium sources
(Trans Tech Publications LTD, 2004)Cordierite ceramics were produced by using local magnesium sources. Mixtures were sintered at different temperatures to examine formation of cordierite. a-cordierite was formed as a major phase over 1150degreesC. High bulk ... -
Catalytic pyrolysis of biomass: Effects of pyrolysis temperature, sweeping gas flow rate and MgO catalyst
(Pergamon-Elsevier Science LTD, 2010)Cotton seed, as a biomass source, is pyrolysed in a tubular fixed-bed reactor under various sweeping gas (N(2)) flow rates at different pyrolysis temperatures. In the non-catalytic work, the maximum bio-oil yield was ... -
Bio-oil production from rapid pyrolysis of cottonseed cake: product yields and compositions
(Wiley, 2006)Fixed-bed fast pyrolysis experiments have been conducted on a sample of cottonseed cake to determine the effects of pyrolysis temperature, heating rate and sweep gas flow rate on pyrolysis yields and chemical compositions ... -
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 ... -
Fast pyrolysis of sesame stalk: yields and structural analysis of bio-oil
(Elsevier Science BV, 2004)Sesame stalk pyrolysis experiments were conducted in a fixed-bed reactor in an attempt to determine the effects of pyrolysis temperature, particle size, heating rate and sweeping gas (N-2) flow rate on the product yields ... -
A Statistical Study of Fatigue Life Prediction of Fibre Reinforced Polymer Composites
(Ismithers, 2011)In this study, the tension-tension fatigue response of bidirectional woven E-glass fibre reinforced unsaturated polyester composites was experimentally determined. The composite parts were produced via continuous laminating ... -
Processing and characterisation of three-layer alumina-based composites with enhanced damage tolerance
(Elsevier Sci LTD, 2005)Three-layer alumina-based composites reinforced with iron in the inner layer and with chromium in the outer layers were fabricated by first uniaxially pressing the three-layer assembly, followed by cold isostatic pressing ... -
The use of pumice (pumicite) in transparent roof tile glaze composition
(Elsevier Sci LTD, 2006)In this study, the use of pumice as an alternative fluxing agent instead of Na-Feldspar in the transparent roof tile glaze composition was investigated. The experiments were designed as a mixture experiment. According to ... -
Electrophoretic deposition of nano-sized BaTiO3
(Springer, 2006)In this study, a non-aqueous method in a simple one pot reaction process was employed to synthesize nano-sized BaTiO3 particles and then electrophoretic deposition technique was employed for thin film coatings. In the first ... -
