摘要
A method of casting an ingot includes the following steps: place solid silicon raw materials on a bottom of a containing device, wherein the containing device includes a container and a graphite layer provided on a surrounding wall and an inner bottom of the container, and the solid silicon raw materials are stacked upon the graphite layer on the inner bottom; heat the container to melt the solid silicon raw material into liquid state; cool the container from the bottom up till all of the silicon raw materials are crystallized and solidified. The solidified silicon raw materials become an ingot. Whereby, the graphite layer can effectively prevent impurities of the container from contaminating the ingot.
