Název v původním jazyce

Microstructural investigation and thermal shock behaviour of mullite-cordierite refractory materials

Popis výsledku v původním jazyce

The characterization of thermal shock damage in cordierite-mullite refractory plates used as substrates in fast firing of porcelain whiteware has been investigated. Two different refractory compositions (termed REFO and CONC), characterised by differentsilica to alumina ratios, were studied. Thermal shock damage was induced in as-received samples by water-quenching tests from 1250°C. Thermal and mechanical properties were determined by means of standard techniques measured at room temperature and thenthe thermal shock resistance parameter R was calculated. The fracture toughness of selected samples was measured by the chevron notched specimen technique. The reliability of this technique for evaluation of small differences in fracture toughness aftera given number of thermal shock cycles was investigated. The suitability of KIc measurements by the chevron-notched specimen technique to characterize the development of thermal shock damage in refractory materials was proved in this ...
