Mechanical properties and thermal shock behaviour of alumina-mullite-zirconia and alumina-mullite refractory materials by slip casting
(Elsevier Sci LTD, 2003)Strength and modulus values of slip-cast alumina-mullite-zirconia and alumina-mullite refractories have been determined as a function of quench temperature by air and water quenching. The resistance to fracture initiation ... -
The effect of mullite on the mechanical properties and thermal shock behaviour of alumina-mullite refractory materials
(Elsevier Sci LTD, 2003)Mechanical properties and thermal shock behaviour of slip-cast alumina-mullite refractories have been investigated. There was a marked improvement in strength, Young's modulus and fracture toughness values with the addition ... -
The microstructural features of an alumina-mullite-zirconia refractory material corroded by molten glass
(Elsevier Sci LTD, 2003)An alumina-mullite-zirconia refractory penetrated by a standard soda-lime-silica glass was statically tested at 1370 degreesC for 72 h. Microstructural features and EDAX analysis of the compositions in the corroded region ... -
The effect of metal coating on the strength of capacitor-discharge joining of oxide ceramics
(Trans Tech Publications LTD, 2004)The Surfaces of alumina and zirconia tiles were sputter coated with various metallic films (Al, Ti, Al+Y and Nb) and were joined by a capacitor-discharge technique using either Al, Ti or Nb as interlayer materials. The ... -
Use of concentrator wastes of Etibor Kirka Borax company in soft porcelain opaque glazes as an alternative fluxing agent
(Trans Tech Publications LTD, 2004)Both manufacturers and customers in ceramic sector like all industrial branches always demand high quality products with less cost. With the increase in consumption levels of final products the considerable decreases in ... -
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 ... -
Effects of Aydin Cine region's albite flotation wastes on the properties of floor tile bodies
(Trans Tech Publications LTD, 2004)Within the scope of determining new possible application fields of waste materials albite flotation wastes, being ore treatment outcome, of Aydin Cine region of Turkey, where very rich feldspar deposits are available, have ... -
Production and characterisation of iron-chromium pigments and their interactions with transparent glazes
(Elsevier Sci LTD, 2003)In this study, production and characterisation of pigments by using less expensive raw materials such as limonite and chromite was undertaken. The resulting pigments were characterised by using X-ray diffraction (XRD) and ... -
Utilisation of concentrator wastes of etibor Kirka Borax Company in the recipe of an opaque frit used for wall tile glazes as an acid boric replacement
(Trans Tech Publications LTD, 2004)Turkey holds similar to63% of total boron deposition shares of the world with 803 million tons. Eti Holding, being the most important producer, possesses 31% of total world production on the B2O3 basis. Like every other ... -
Glass-ceramic glazes in the CaO-SiO2 system
(Trans Tech Publications LTD, 2004)Glass ceramic glazes were developed in the system of CaO-SiO2 system. Compositions containing B2O3 and K2O as fluxing agent were melted at 1450degreesC and fritted. Glazes for porcelain tiles were formulated by using these ... -
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. ... -
Reaction model for the boron carbide/aluminium system
(Trans Tech Publications LTD, 2004)An attempt has been made to shed light on the reaction mechanism during the production of B4C/Al composites by making use of the measured phase contents of the phases B4C, Al, Al3BC and AlB2. It was found that the agreement ... -
Synthesis of the CeO2 based pigments by using enriched rare-earth oxides located at Eskisehir Kizilcaoren region
(Trans Tech Publications LTD, 2004)Pigments based on CeO2 structure are known to give various pink-orange and red brown colour in ceramic glazes. This type of pigments is prepared by high temperature calcination Of CeO2 and Pr6O11 with admixed rare-earth ... -
Processing of textured zinc oxide varistors via templated grain growth
