摘要
TiO2 powder samples with an average particle size of 50 nm were sintered in air at 1200 degrees C at different heating rates of 1, 3, 5 K min(-1). The apparent sintering activation energy was determined from dilatometer shrinkage data using the Arrhenius theory. The results give an activation energy of 115 /- 10 kJ mol(-1) for the present material, which is in good agreement with values reported in the literature. It is concluded that the constant rate of heating method can be used to measure activation energy.
