What is the density of silica sand? - Quora

Answer (1 of 2): While the density of silica is 2.65 g/cc, the average density of silica sand will be lower and depend on its origin. Rounded grains of approx. uniform diameter (eg sea sand) will have greater porosity, hence lower density than a 'sharp' sand with a wide range of particle sizes wh...

Why Chromite Sand | Minerals Technologies Inc.

Silica Sand undergoes an alpha-beta phase transformation at approx 350oC – 650oC. This corresponds to the temperature zone that the mould experiences during cooling. This can lead to expansion defects such as veining or cracking in castings where silica sand moulds are used Chromite has a much lower expansion over the same temperature range.
