Fayalite then solidifies around the grains, gluing the sand onto the surface of the casting. The role of iron oxide in preventing porosity has long been linked with its ability to react with silica to form fayalite, which forms a "physical" barrier, preventing gas solution. Most foundrymen were taught that seacoal acts by burning and producing a reducing atmosphere, which prevents oxidation of the cast iron, and consequently prevents the formation of fayalite and ultimately Penetration. |
