The sand casting method falls into the latter category. Silica sand is the preferred moulding aggregate in sand casting, since it is readily available and is cheap worldwide. Foundry silica sand with a size distribution of between 50 and 60 AFS (220 to 250 microns) produces moulds with a good surface finish that requires low binder additions.

The production of sand fillers is simple because it includes, at most, only washing and classification into grades differing in grain size. Because sand has a negligible degree of porosity, it has an extremely low specific surface area in the range from 40 to 160 cm 2 /g. The material usually contains more than % SiO 2, with absorbed water being at a negligible level (%).
