Description Development of alumina/glass composites with minimal residual porosity and superior mechanical properties requires systematic studies on glass infiltration into porous alumina. This work has examined the effect of alumina particle size and the resulting pore size distribution on glass infiltration. Samples were prepared by slip-casting a coarser alumina powder and blends of the coarse (d50 similar to 3.4 mu m) and a finer (d50 similar to 0.7 mu m) alumina powder. After presintering (1200 degrees C) and following a single cycle of infiltration (1100 degrees C), the sample with 50:50 (wt%) coarse and fine alumina showed highest flexural strength. Improvement in flexural strength could be imputed to the better glass infiltration.
