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 is only used with expensive alloy steel casting and to make cores. Zircon sand
