Thermal fatigue resistance of open cell ceramic foams

Kiln Furnitures

“…5, the data still fall on the same curve as those for 14 % dense material. This is in agreement with Vedula et al [7][8][9], who stated that thermal shock resistance of ceramic foam is not a strong function of density. The projected strength of the higher density YZA at 10 000 cycles is over 700 kPa.…”

“…The struts themselves are much smaller and weaker as a result, and cannot hold up to the stresses generated in the grinding process, so they tend to break instead of being polished. In addition, the thermal shock resis- tance of the foam is reduced as the pore size is decreased, as shown by Vedula et al [7][8][9], and this is an undesirable characteristic. For these cases, experimental reticulated kiln furniture is being tested.…”

Thermal shock resistance analysis of a semi-infinite ceramic foam

“…A number of interesting observations were made during the research works aiming at investigating the thermal shock resistance. The thermal shock resistance analysis of ceramic media was mainly focused on the measuring and calculating of Young's modulus and retained strength after thermal shock (Dimitrijevic, Posarac, Majstorovic, Volkov-Husovic, & Matovic, 2009;Ding, Zeng, & Jiang, 2006;Kan, Wei, Meng, & Xu, 2009;Orenstein & Green, 1992;Rendtorff, Garrido, & Aglietti, 2011;Vedula, Green, & Hellman, 1998;You et al, 2005), the length of crack growth (Panda, Kannan, Dubois, Olagnon, & Fantozzi, 2002;Yuan, 2008), and thermal stress resistance parameter (R 0 f ) (Vedula, Green, & Hellman, 1999). It is essential to establish theoretical models for the evaluation of thermal shock resistance behavior of these advanced materials.…”

Mechanical and thermal shock behavior of refractory materials for glass feeders

“…Therefore it is of interest to evaluate the behavior of a certain material after several thermal shock treatments. Thermal fatigue resistance (TFR) evaluation [19][20][21][22][23][24] consists in the measurement of a certain characteristic property of a material with successive thermal shock treatments. Both the experimental evidence and the theoretical models show certain saturation behavior for the TFR of ceramic materials.…”
