Effect of ZrSiO4 on the corrosion behavior of MgO-FeAl2O4 composite refractory materials
(Carl Hanser Verlag, 2016)
In this study, the corrosion behavior of refractory materials that were produced by incorporating ZrSiO4 (zircon) at different ratios into MgO-FeAl2O4 (hercynite) were investigated. The values of density and open porosity ...
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, ...
Microstructural Characterisation and Investigation of the Effects of ZrSiO4-Y2O3 Additions on Corrosion Behaviour of MgO-Spinel Composite Refractories
(Trans Tech Publications LTD, 2012)
Corrosion resistance of MgO-Spinel (M-S) composite refractories containing various amounts of ZrSiO4-Y2O3 constituents was investigated. Density and open porosity values were measured and evaluated. Corrosion tests of ...
Spinel formation, reaction conditions and densification properties of magnesia-spinel composites
(Trans Tech Publications LTD, 2004)
Densification, reaction conditions and properties of densified MgO and spinel composites were examined using both pressureless sintering and hot-pressing. Initially fine (32 nm) MgO powder, either alone or blended with mum ...
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 ...
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 ...
Developments on the mechanical properties of MgO-MgAl2O4 composite refractories by ZrSiO4-3 mol% Y2O3 addition
(Elsevier Sci LTD, 2012)
Improvements and the effects of additions of ZrSiO4-3 mol% Y2O3 into MgO-MgAl2O4 composite refractories on mechanical properties and thermal stress resistance parameters were investigated. Significant improvements were ...
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. ...
