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, ...
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 ...
Improvements on corrosion behaviours of MgO-spinel composite refractories by addition of ZrSiO4
(Elsevier Sci LTD, 2012)
Corrosion behaviours of MgO-spinel-ZrSiO4 compositions were investigated. The influence of corrosion resistance based on the microstructural changes occurred due to the solubilities of constituents in corroded regions was ...
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 ...
Improvements on the mechanical properties and thermal shock behaviours of MgO-spinel composite refractories by ZrO2 incorporation
(Elsevier Sci LTD, 2012)
Microstructural features and improvements on the mechanical properties and thermal shock behaviours of MgO-spinel composite refractories with ZrO2 addition were examined. ZrO2 incorporation into MgO-spinel led to improvements ...
Improvements on the thermal shock behaviour of MgO-spinel composite refractories by incorporation of zircon-3 mol% Y2O3
(Elsevier Sci LTD, 2012)
The effects of incorporations of zircon-3 mol% Y2O3 (Y) into MgO-spinel (M S) compositions to improve mechanical properties and thermal shock behaviour were investigated. Mechanical properties were measured, R R parameters ...
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. ...
Corrosion behavior of MgO-MgAl2O4-FeAl2O4 composite refractory materials
(Australian Ceramic Society, 2017)
This paper investigated the corrosion behavior of refractory materials that were produced by incorporating hercynite (FeAl2O4, H) at different ratios into MgO-MgAl2O4 (spinel, S). Meanwhile, the values of density and open ...
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 ...
