Influence of grinding on the sintering properties of Rutile

It has been shown that the grinding of Rutile reduces the starting sinterin g temperature of compacted bodies. A compactness close to full density has been obtained for both the ground and the whole set of Rutile ground sample s. SEM observations have shown that the grain size of the compacted bodies decreases by increasing the grinding time of the powders used as raw materi als. These results have been interpreted considering that the grinding of R utile inhibits its grain growth during the sintering, (C) 2001 Elsevier Sci ence B.V. All rights reserved.
