Foundry Sand - an overview ScienceDirect Topics

Molding sands are manufactured by using virgin silica sands with the addition of binding agents (e.g., bentonite clay and organic resins). Silica sand is mainly used because of its thermal conductivity. It can absorb and transmit heat while allowing the gases generated during the thermal degradation of binders to pass through the grains.
