Subeutectic Densification and Second-phase Formation in Al₂O₃CaO
Green, David J. and Halloran, John and Johnson, David W. and Klein, Lisa
The early and intermediate stages of densification of alumina containing calcia were examined at subeutectic temperatures. Up to 0.15 wt% calcia causes a decrease in the densification rate; from 0.15 to 0.7 wt% calcia, the densification rate increases initially but then decreases at longer times; more than 0.75 wt% calcia leads to a monotonically decreasing densification rate. the data for materials containing more than 0.15 wt% calcia may be interpreted as a competition between enhanced subeutectic densification and the presence of densification-retarding second phases.
