Preparation of cordierite ceramics from talc with boron oxide addition
(2004)Thermal reactions of impure materials of talc, silica and alumina with moderate particle sizes were investigated to obtain a dense cordierite ceramic by boron oxide addition as a sintering aid. Mixed powders were uniaxially ... -
Preparation, Characterization and Catalytic Properties of SBA-15-SO3H Supported Tungstophosphoric Acid for Esterification Reaction
(Polish Acad Sciences Inst Physics, 2017)SBA-15-SO3H supported tungstophosphoric acid (TPA, H3PW12O40) mesoporous materials were synthesized by impregnation of TPA into the hydrothermally synthesized SBA-15-SO3H and the catalytic performances were compared for ... -
Pressing behaviour of spray dried alumina-zirconia granules
(Trans Tech Publications LTD, 2004)In this study, spray drying of alumina-zirconia slurries on a pilot scale, and their pressing behaviour were investigated. Slurries were prepared at 50 wt-% solid loading. An acrylic polymer emulsion, polyethylene glycol, ... -
Pressureless Melt Infiltrated Non-Oxide Ceramic-Metal Composites
(Trans Tech Publications LTD, 2009)In the present study highly dense (open porosity < 1 %), light-weight (d <= 2.85 g/cm(3)) and Al(4)C(3)-free non-oxide ceramic-metal composites were produced at comparatively low temperatures (<= 1250 degrees C) by pressurless ... -
Pressureless sintering of Al2O3-TiCN composites
(Trans Tech Publications LTD, 2004)A composition of 70 wt % Al2O3 + 30 wt % TiCN was prepared and pressureless-sintered at temperatures ranging from 1700 to 1840degreesC. In order to achieve densification, a powder bed was also employed. The resultant ... -
Pressureless sintering of hexagonal boron nitride powders
(Trans Tech Publications LTD, 2007)Pressureless sintering of hexagonal boron nitride (BN) with and without additives was performed using a powder which was previously nitrided at 900 degrees C and then heat treated at 1400 degrees C. Sintering additives ... -
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 ... -
Production and characterisation of pigments produced using grinding waste from cast iron foundry
(Trans Tech Publications LTD, 2004)The brown and black pigments are generally synthesised from different powders such as iron (111) and chromium (111) oxide powders. In this study, iron-chromium pigments by using grinding waste from cast iron foundry as ... -
Production and industrial adaptation of fast single firing wall tile opaque glass-ceramic glazes containing borax solid wastes
(2008)Zircon (zirconium silicate) is the main opacifier of glossy, opaque, white colored, frit-based wall tile glazes. However, zirconia containing frits employed in the preparation of these glazes increase the production cost ... -
Production of alpha-beta SiAlON-TiN/TiCN composites by gas pressure sintering
(Belgian Ceramic Society, 2004)Due to the favorable properties possessed by novel alpha-beta SiAlONs, they are attractive materials for cutting tool applications. Such applications require materials with high hardness, high fracture toughness and high ... -
The production of beta-SiAlON ceramics with low amounts of additive, at low sintering temperature
(Elsevier Sci LTD, 2010)In the present work nano-sized powder of beta-SiAlON was produced using a wet milling process. Different milling times and mediums (methyl ethyl keton, ethanol and toluene as solvents, polyethyleneglicol, oleic acid, sodium ... -
Production of blue willemite based pigments by using ZnO powder produced from metal slags
(Trans Tech Publications LTD, 2004)In this study, production of pigments by adding different amount of Co and calcination at different temperatures were under-taken. Co-willemite blue pigments were produced by using ZnO powders produced from metal slags. ... -
Production of brown pigments for porcelain insulator applications
(Elsevier Sci LTD, 2006)In this study, production of brown pigment for the ceramic insulator applications by using inexpensive natural raw materials or waste materials was undertaken. Different pigment compositions were designed, synthesised and ... -
Production of coloured zircon pigments from zircon
(Elsevier Sci LTD, 2007)Zircon (ZrSiO4) pigments are commonly used in the ceramic industry for glazes due to their high chemical stability and superior resistance to the dissolution during firing in glazes. These pigments are made by calcining a ... -
