Description
Summary:Up to 0.15 wt% CaO decreases the densification rate; at 0.15- 0.7 wt%, the densification rate increases initially but then decreases; > 0.75 wt% leads to a monotonically decreasing densification rate. The data for materials containing > 0.15 wt% CaO support the view that a competition occurs between enhanced subeutectic densification and the presence of densification-retarding second phases.
