Sintering Behavior of Titanium Wire Containing Pellets Figure 4.23 shows the relative shrinkage curves for alumina samples, which titanium wire containing at 1350 o C. For the behavior of relative shrinkage, Figures 4.1 and 4.23 are compared and there is no difference. It is clear that the titanium wire does not affect the shrinkage behavior of alumina.
