Chromite Sand In Silica Sand

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.

Chromite an overview ScienceDirect Topics

Most chromite sand is derived from crushed ore, and so as well as being therefore rather angular, dust is created during conveyance which in turn increases the risk of reaction with silica sand. In general, it is estimated that 20–30% of chromite sand is lost each time that the sand is reused.
