Mechanical Properties of Alumina Porcelain during Heating
Original language description
The mechanical strength and Young?s modulus of green alumina porcelain (50 wt. % of kaolin, 25 wt. % of Al2O3, and 25 wt. % of feldspar) were measured during heating up to 900 °C and 1100 °C, respectively. To this end, we used the three point-bending method and modulated force thermomechanical analysis (mf-TMA). The loss liberation - of the physically bound water (20 ? 250 °C) strengthens the sample and Young?s modulus increases its values significantly. The dehydroxylation that takes place in the rangeof 400 ? 650 °C causes a slight decrease in Young?s modulus. On the other hand, the mechanical strength slightly increases in this temperature range, although it has a sudden drop at 420 °C. Beyond the dehydroxylation range, above 650 °C, both Young?s modulus and mechanical strength increase. Above 950 °C, a sharp increase of Young?s modulus is caused by the solid-state sintering and the new structure created by the high-temperature reactions in metakaolinite.
