Production of bio-fuels from cottonseed cake by catalytic pyrolysis under steam atmosphere
(Pergamon-Elsevier Science LTD, 2006)
The purpose of this study is to evaluate the amounts of catalytic pyrolysis products of cottonseed cake in steam atmosphere and investigate the effects of both zeolite and steam on pyrolysis yields. The effect of steam was ...
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 ...
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 ...
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 ...
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 ...
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 ...
Reaction-bonded aluminium oxide (RBAO) process: II, the solid-state oxidation of RBAO compacts
(2000)
The oxidation kinetics and the fraction of aluminum that is oxidized via solid-gas reaction in reaction-bonded aluminum oxide (RBAO) compacts are shown to be strongly dependent on the oxidation temperature and the ...
Mechanical properties of magnesia-spinel composites
(2002)
A set of dense magnesia-magnesium aluminate spinel composites has been prepared by hot-pressing magnesia powder using 0 to 30 wt.% of spinel powder of mean particle size 3, 11 and 22 µm. Bend stength, modulus, and fracture ...
The characterization and the utilization of the waste clays from gümüşköy silver mine in brick industry
(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 ...
