A Silver Ion-doped Calcium Phosphate-based Ceramic Nanopowder-coated Prosthesis Increased Infection Resistance
(Springer, 2013)Despite progress in surgical techniques, 1% to 2% of joint arthroplasties become complicated by infection. Coating implant surfaces with antimicrobial agents have been attempted to prevent initial bacterial adhesion to ... -
Microstructure-property relationship in textured ZnO-based varistors
(Pergamon-Elsevier Science LTD, 2010)The relationship between microstructure texturing and electrical characteristics of a ZnO-based varistor system was investigated in comparison with a varistor system having the same chemical composition but conventional ... -
Chemical stability of KNbO3, NaNbO3, and K0.5Na0.5NbO3 in aqueous medium
(Wiley, 2018)In recent years, potassium sodium niobate (K0.5Na0.5NbO3, KNN) has become popular and promising among perovskite lead-free piezoceramic systems. In this study, the chemical stability of KNN powders in aqueous medium was ... -
Fabrication and microstructural stability of spark plasma sintered Al2O3/Er3Al5O12 eutectic
(Elsevier Sci LTD, 2015)Al2O3-Er3Al5O12 (BAG) eutectic was prepared by a arc melting process under Ar atmosphere. Button shaped melts, containing fine sized irregular eutectic structures of 'Chinese script', with interpenetrated Al2O3 and EAG ... -
Silver ion doped ceramic nano-powder coated nails prevent infection in open fractures: In vivo study
(Elsevier Sci LTD, 2016)Background: Despite improvement in operative techniques and antibiotic therapy, septic complications still occur in open fractures. We developed silver ion containing ceramic nano powder for implant coating to provide not ... -
Zircon-free frits suitable for single fast-firing opaque wall tile glazes and their industrial productions
(Elsevier Sci LTD, 2009)Wall tile glazes with a smooth surface texture, high glossiness, and whiteness are usually based on zirconium containing frits. However, these frits are quite expensive and therefore, there have recently been certain ... -
Production of opaque frits with low ZrO2 and ZnO contents and their industrial uses for fast single-fired wall tile glazes
(Springer, 2009)The amounts of zirconium and zinc oxides, which raise the production costs of ceramic glazes, were decreased in fast single-fired wall tile frit compositions and an industrial frit production was conducted. Opacity of the ... -
Evaluation of borax solid wastes in production of frits suitable for fast single-fired wall tile opaque glass-ceramic glazes
(Indian Acad Sciences, 2010)Zircon (zirconium silicate, ZrSiO(4)) is the main opacifier of glossy, opaque, white-coloured, frit-based wall tile glazes. However, zirconia containing frits employed in the preparation of these glazes raise the production ... -
An investigation of the effect of alkaline oxides on porcelain tiles using factorial design
(Korean Assoc Crystal Growth, Inc, 2012)In this study, the effect of alkaline oxides (MgO, CaO, Na2O and K2O) was investigated in porcelain tile compositions. Talc (MgO) and dolomitic clay (CaO, MgO) were added to porcelain tile compositions instead of feldspar ... -
A critique of master sintering curve analysis
(Elsevier Sci LTD, 2018)In this work, we explore factors affecting the accuracy of the master sintering curve (MSC) approach for analyzing the complete sintering profile of ceramic powders. We show that the instantaneous anisotropic shrinkage ... -
Co-doped willemite ceramic pigments: Technological behaviour, crystal structure and optical properties
(Elsevier Sci LTD, 2010)Cobalt-doped willemite is a promising blue ceramic pigment, but some important aspects concerning crystal structure, optical properties and technological behaviour are still undisclosed. In order to get new insight on these ... -
CVD growth of monolayer MoS2: Role of growth zone configuration and precursors ratio
(IOP Publishing LTD, 2017)Single-layer, large-scale two-dimensional material growth is still a challenge for their wide-range usage. Therefore, we carried out a comprehensive study of monolayer MoS2 growth by CVD investigating the influence of ... -
Effect of the milling process on the properties of CoFe2O4 pigment
(Elsevier Sci LTD, 2013)In this study, CoFe2O4 pigments were synthesised using both co-precipitation and conventional ceramic methods. Pigment particles prepared using the conventional ceramic method were subsequently milled to submicron size. ... -
Pyroplastic deformation behavior of vitreous porcelain bodies in presence of spodumene
(Australian Ceramic Society, 2017)Pyroplastic deformation tendency of vitreous body compositions is a major production problem. In this work, a vitreous sanitaryware body composition (ST) which was developed in a previous work was taken as standard, and ... -
Effect of the processing on the production of cordierite-mullite composite
(Elsevier Sci LTD, 2010)In this study, effect of process on the production of cordierite mullite composite was studied. For this reason two different processing methods were used in the production of cordierite mullite composites. In first process, ... -
Production of cordierite ceramic by aqueous tape casting process
