Fs. Shiau et al., EFFECTS OF MILLING AND PARTICLE-SIZE DISTRIBUTION ON THE SINTERING BEHAVIOR AND THE EVOLUTION OF THE MICROSTRUCTURE IN SINTERING POWDER COMPACTS, Materials chemistry and physics, 57(1), 1998, pp. 33-40
In this investigation, it was observed that the contamination arising
from the milling medium has a great influence on the sintering behavio
r. The densification rate of the powder milled with ZrO2 balls is larg
ely inhibited, and the activation energy of ZrO2-doped alumina is sign
ificantly enhanced. The possible reasons for the enhancement of the ac
tivation energy were discussed. The effects of particle size distribut
ion of powder compacts on the microstructural evolution of alumina dur
ing sintering were proposed and discussed. (C) 1998 Elsevier Science S
