Silica Sand - an overview ScienceDirect Topics

Chemically bonded sand consists of silica sand and chemical binder that is activated by a catalyst. Commonly, they are used in core making where high strengths are necessary to withstand the heat of molten metal, but also in mold making. Silica sand is thoroughly mixed with the chemicals; a catalyst initiates the reaction that cures and hardens the mass.
