摘要：
Novel alumina based refractories are investigated to determine thermo-mechanical properties within the framework of the DFG SPP "FIRE". The refractories are developed for the application as slide gates or entry nozzles. Experiments were performed from RT 1000 degrees C. Wedge splitting tests were used to determine the R-Curve behavior and quantify the fracture resistance. A comparison with crack growth observed in situ at RT in a SEM chamber permitted to get insight into the crack shielding mechanism. In addition elastic behavior was investigated using impulse excitation technique. The thermal shock resistance has been calculated and compared to a standard refractory material. The influence of the used additives (TiO2, ZrO2) on elastic behavior, crack propagation and thermal shock resistance has been investigated. Addition of small amounts of these oxides leads to large changes in elastic modulus and thermal shock resistance. The additives also lead to different R- curve behavior compared to undoped alumina.
