10.10 Suppose that in order to reduce sintering shrinkage you were to mix enough fine particles (about 30%), 1 micron in diameter, with coarse particles, 50 microns in diameter, so that all the interstices between the coarse particles were filled with fine particles. What would be the rate of shrinkage of this compact? Make a plot of log (L/Lo) versus log t, and place the 1-micron powder and 50-micron powder shrinkage lines in their relative positions; then place the shrinkage curves for the composite material in its proper position with respect to the l-micron and 50-micron curves. Justify your
