(Trans Tech Publications LTD, 2004)This study aims to improve the understanding of formation of mullite from kaolin at low process temperature using different sintering regimes. The optimum parameters affecting mullite formation from kaolin such as sintering ... -
Development of laminar type functionally graded SiAlON ceramics
(Trans Tech Publications LTD, 2004)In order to combine high hardness with high toughness, laminar type (two layers) functionally graded (FGM) SiAlON ceramics were developed. In a previous study achieved by the same authors, presence of a sharp transition ... -
The effect of boron waste in phase and microstructural development of a terracotta body during firing
(Elsevier Sci LTD, 2006)In the present study, a dewatering sieve waste (TSW) of Etibor Kirka Borax company (Turkey) was employed in different amounts in order to develop an experimental terracotta floor tile body composition in combination with ... -
Interactions between a leadless glaze and a biscuit fired bone China body during glost firing - part III: effect of glassy matrix phase
(Elsevier Sci LTD, 2003)As the final part of the study, the interactions between a commercial leadless glaze and a simulated bone china body glass during glost firing at different temperatures have been investigated. Advanced techniques such as ... -
Utilization of coal combustion fly ash in terracotta bodies
(Trans Tech Publications LTD, 2004)In this present work, coal combustion fly ash from a power plant in Turkey was used in combination with a traditional raw material in terracotta production with the aim of having a product with improved physico-mechanical ... -
Interactions between a bismuth type leadless glaze and a bone China body during glost firing
(Trans Tech Publications LTD, 2004)In the present study, the interactions between a high bismuth type commercial transparent leadless glaze and a biscuit fired bone china body during glost firing at different temperatures were investigated using SEM. The ... -
Computational analysis on cymbal transducer
(Taylor & Francis Inc, 2003)Finite Element Analysis in collaboration with experimental studies was conducted to investigate the effects of dimensional parameters on the performance of the cymbal transducer. ANSYS 5.5 FEM code was used for computational ... -
Pyrolysis of two different biomass samples in a fixed-bed reactor combined with two different catalysts
(Elsevier Sci LTD, 2006)Pyrolysis of Euphorbia rigida and sesame stalk biomass samples with two selected commercial catalyst, namely DHC-32 and HC-K 1.3Q, have been conducted in a fixed-bed reactor. The effect of different catalysts and their ... -
Development of a multipurpose tile body: Phase and microstructural development
(Elsevier Sci LTD, 2006)In this study, an attempt was made in order to develop a multipurpose tile body using a single formulation. In order to achieve this, several body recipes were prepared using mainly local raw materials with clearly defined ... -
Investigation of borax waste behaviour in tile production
(Elsevier Sci LTD, 2007)Although there are various studies published in the relevant literature on the use of borates in tile production, borax waste has been mainly used in place of feldspar and the results showed that borate migration to the ... -
Fracture toughness of alumina/lanthanum titanate laminate composites with a weak interface
(Elsevier Science BV, 2007)Layers of lanthanum titanate (La2Ti2O7) and alpha-alumina (alpha-Al2O3) were employed to form a layered composite in order to improve the fracture toughness of monolithic alumina. The composites were produced by two different ... -
Optimizing mechanical quality factor of cymbal transducer
(Taylor & Francis LTD, 2006)In general, high mechanical quality factor 'Q(m),' which is the indication of low loss, is a desired property for transducers. However, low Q(m) and wide bandwidth are desired properties for underwater transducer. Therefore, ... -
Lanthanum titanate (La2Ti2O7) as an interphase material in alumina (Al2O3) based composites
(Trans Tech Publications LTD, 2004)The aim of this research is to fabricate and characterize alumina (Al2O3) / lanthanum titanate (La2Ti2O7) laminate ceramic composites. The interfacial bond between oxide laminates has a critical effect on the final mechanical ... -
Joining of SiAlON ceramics to pyrex glass
(Belgian Ceramic Society, 2004)In the present study, pressureless joining of gas pressure sintered (alpha-beta)-SiAlON ceramics to pyrex glass was investigated. Preoxidized SiAlON ceramics were used to enhance wettability and provide chemical compatibility ... -
Investigation of sanitaryware scrap behaviour in terracotta bodies
(Trans Tech Publications LTD, 2004)In this paper, an investigation into a potential use of unfired body scrap from a local sanitaryware manufacturer in commercial terracotta production was presented. Experiments were achieved under laboratory conditions by ... -
