Abstract

Modifying agent for graphitisation of cast iron in the manufacture of high quality castings has the chemical composition Si 64%, C 20%, Cu 8.31%, Ca 3.6% and Al 1.5%. Specifically, the carbon is introduced into the raw material for producing the modification agent in the form of granular graphite, obtained from graphite electrides with a high carbon content.
