ABSTRACT:
This specification is directed to a method of reducing the green density of an article cast from a casting slip containing silicon metal particles. The method is characterized by the step of adding to the casting slip ingredients a cationic polymer having a molecular weight in a range from 1,000 to 50,000. The cationic polymer is effective in the casting of the slip to form bridges between the silicon metal particles which keeps the particles from packing so closely together, whereby the green density of the cast article is lower and the article is more easily nitrided completely in thick section articles.
