Abstract
ABSTRACTIn this work it was conducted a pre heat treatment of a number of samples of alumina with organic binder in order to remove most of the organic phase. The treatment showed no effect on the physical properties of test specimens; green bodies remained stable during sintering process. Preheating at 100 °C for 4 h followed by heating at 300 °C for 4 h were the most favorable conditions to avoid formation of defects in the sintered pieces.
