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.

Chrome Sand Applications in Mutiple Industries. Chrome sand is one of the most widely used refractory materials, and is available in high purity from African Pegmatite as part of a wide catalogue of high performance refractories. Chrome sand is a naturally occurring mineral that consists mainly of the oxides of iron and chromium.
Of all types of filler sands, Chromite-based sands are the most used. For the most part, the most important properties of a filler sand are particle-size distribution, low thermal expansion, flexibility, refractoriness, composition, and packing.These properties have a significant impact on the formation of the sintered crust and its properties when the filler sand makes contact with liquid steel.
