Sand casting - Wikipedia

Chromite sand. Chromite sand is a solid solution of spinels. Its advantages are a low percentage of silica, a very high fusion point (1,850 °C (3,360 °F)), and a very high thermal conductivity. Its disadvantage is its costliness, therefore it's only used with expensive alloy steel casting and to make cores. Zircon sand

Why Chromite Sand | Minerals Technologies Inc.

The Thermal Conductivity of chromite sand is higher than the other commercially available foundry moulding sands. This results in a mild chilling of the surface and a thicker solidified skin. This thicker skin improves the casting surface and reduces the likelihood of casting defects. Generally, foundries use Chromite Sand for one of the ...
