Development of Young's Modulus of the Green Alumina Porcelain Raw Mixture
Original language description
Young?s modulus of a green mixture (50 wt. % of kaolin, 25 wt. % of Al2O3, and 25 wt. % of feldspar) was measured during heating using a resonant method. It was found that the liberation of the physically bound water (20 °C ? 250 °C) strengthens the sample and Young?s modulus increases 30 %. On further heating, Young?s modulus continuously decreases up to 700 °C when Young?s modulus begins to rise. Above 950 °C, a steep increase of Young?s modulus is caused by the solid-state sintering and a new structure created by the high-temperature reactions in metakaolinite. A dehydroxylation, which takes place in the range of 400 °C ? 650 °C does not influence Young?s modulus.
