SINTERING OF TITANIUM DIOXIDE,
MICHIGAN UNIV ANN ARBOR
Experiments were performed on the rate of growth of the neck formed between titanium dioxide single crystal spheres, at constant temperature and different surrounding gas atmospheres. These included air and mixtures of H2 H20 from 11 to 120. The temperature range in vestigated was 900 to 1350C. A kinetic analysis of the data shows that the predominant contribution to the sintering of the microspheres stems from a plastic flow mechanism. Supporting qualitative evidence for this conclusion is presented. Whisker growth during sintering of titania was observed and the effect of this growth on sintering is discussed. Author
