For a given weight of metallic powders, the total surface area of the powders
is increased by which two of the following? - correct answer Smaller particle
size and higher shape factor
Techniques for reducing particle size in ceramics processing involve
mechanical energy in various forms, referred to by which one of the following
terms? - correct answer Comminution
