| Description
| - Two commercially available refractory ceramic materials primary used as substrates for fast firing of porcelain stoneware were investigated. The first one, commercially known as CONC, contains cordierite and mullite in the ratio 50:50. The REFO refractory composite material with coarser microstructure compared to CONC has a cordierite-to-mullite ratio of 50:45 and the balance is filled by quartz. Both materials were exposed to water-quench tests from 1250°C, applying various numbers of thermal cycles (shocks). Subsequently the fracture toughness was evaluated on both as-received and shocked samples using the Chevron notched specimen technique. The results were analysed with respect to the microstructure damage caused by the thermal loading. Scanning electron microscopy was used to analyse both microstructure and fracture surfaces in samples with different thermal loading history.

- V této práci byly zkoumány dva komerční dostupné žáruvzdorné keramické materiály primární používané jako podložky při rychlém vypalování porcelánu. První z nich, známý pod obchodní značkou jako CONC, má podíl cordieritu a mulitu 50:50. Druhý žáruvzdorný kompozitní materiál, známý jako REFO, vyznačující se hrubší mikrostrukturou v porovnání s CONC, má podíl cordieritu a mulitu 50:45 a zbytek do sta procent je tvořeno křemenem. Oba tyto materiály byly vystaveny různému počtu tepelných šoků tj. opakovanému prudkému ochlazení do vody z teploty 1250°C. Následně byly provedeny zkoušky lomové houževnatosti využívající techniku chevronového vrubu u všech získaných stavù včetně stavu po dodání. Rastrovací elektronová mikroskopie byla použita jak pro analýzu mikrostruktury, tak i lomových ploch u vzorků s různou historií tepelného zatěžování. (cs)
