Effects of Heating Rates on the Sintering Behaviors of Alumina Powders

SONG Jiupeng1,2, Barriere Thierry2, LIU Baosheng1, Gelin Jean-Claude2(1 Department of Applied Mechanics and Engineering, Southwest Jiaotong University, Chengdu 610031,China;2 Laboratroy of Applied Mechanics, Femto-ST Institute, Besancon 25000,France)  
A series of sintering experiments with different heating rates are carried out in dilatometer for the alumina green parts shaped by powder injection molding and debinding. The experimental results show that the densification occurs mainly during the heating periods.Rapid heating is favorable to densification and prohibitive to grain growth.But the final densification is relatively low due to the short sintering time and the maximum sintering temperature of the furnace. The desired results of both densification and microstructure can be attained by employing faster heating rate to pass the low temperature periods and slowing heating rate at the relatively high temperature. The experimental and analytical results make the reference for building the non-isothermal sintering model and for the optimization of sintering process parameters.
