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. ... -
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, ... -
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 ... -
