Effectiveness of Pure Silicon on Inoculation

Abstract

Inoculants for cast irons are usually materials containing silicon. It is important to an understanding of the mechanism of inoculation to establish the effectiveness of silicon in this role. When grey iron is inoculated with a bar of pure silicon, the region near the bar is inoculated while that further away is not affected. Although pure silicon has been found to be an active agent in the inoculation of cast iron, the phenomena of fading is so rapid that the element's inoculating effects were hardly recognised in some former experiments.
