With increasing Al powder paste, porosity, average pore size, and hole shape factor increased, number of holes decreased, and proportion of large holes increased
With increasing slurry fluidity, porosity first increased then slowly decreased, number of holes first decreased then slowly increased
Dry density and compressive strength decreased with increasing porosity
