| Abstract: | Thermal-expansion property of new quartz sands and its baked sands from three different places was measured and analyzed. It is concluded that the thermal-expansions of the baked sands are smaller than those of the new sands, which provides reasonable theoretical basis for foundry processes. |

| Keywords: | quartz sand baking thermal-expansion with temperature thermal-expansion with sharp heating |
