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 ...
Young's modulus measurements of magnesia-spinel composites using load-deflection curves, sonic modulus, strain gauges and Rayleigh waves
(Elsevier Sci LTD, 2003)
The extent of interlinking of the microcracking and a decrease in strength and modulus values were determined to be a function of both spinel particle size and volume fraction to allow calculation of thermal shock parameter, ...
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 ...
Thermal shock behaviour of magnesia-spinel composites
(Elsevier Sci LTD, 2004)
The incorporation of up to 30% of spinel powder of median particle sizes 3, 11 and 22 mum into dense magnesia gives improved resistance to thermal shock as indicated both by the R''' thermal shock resistance parameters ...
Fracture behaviour of magnesia and magnesia-spinel composites before and after thermal shock
(Elsevier Sci LTD, 2004)
Microstructural changes, as a consequence of the thermal expansion mismatch between magnesia and spinel phases, and fracture behaviour of magnesia and spinel composites have been investigated as a function of spinel content ...
Investigation of parameters affecting grain growth of sintered magnesite refractories
(Elsevier Sci LTD, 2005)
The parameters influencing grain size of sintered magnesite such as temperature (1700 and 1800degreesC), time (19 and 50 min), cooling rate (5, 10 and 25degreesC min(-1)) and various particle size (-3; +3,-5; +5,-8; +8,-10 ...
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 influence of zircon in a model aluminosilicate glass tank forehearth refractory
(Elsevier Sci LTD, 2003)
Standard aluminosilicate forehearth refractories are normally fabricated with a small proportion of zircon to improve their performance. To identify possible bases for the action of the zircon, fine-grain aluminosilicate ...
Effect of the particle size distribution of spinel on the mechanical properties and thermal shock performance of MgO-spinel composites
(Elsevier Sci LTD, 2003)
The influence of varying the amounts of spinel with a similar median particle size, but with different distribution, on the mechanical properties and thermal shock performance of MgO-spinel composites was investigated. ...
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 ...
