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.
