On the Sintering Activation Energy of α-Al2O3

摘要：

　　The sintering activation energy of high-purity alumina powders with different particle sizes was evaluated under non-isothermal condition.It was found that,during sintering,the activation energy for the lower temperature stage is higher than that for higher temperature stage.The value of the activation energies for the powder compact with larger particle size was higher than that for the powder compact with smaller particle size.If the selected temperature interval for calculation was narrow enough,the evaluated activation energy values varied with the increasing temperature continuously.
