ABSTRACT:
The invention provides a method for purifying silicon which comprises a step of blowing a treating gas generated by reacting carbon with an oxidized gas into a molten silicon, as well as silicon produced by the method. Carbon can be held in a container, the oxidized gas can be passed through the container, and the oxidized gas can contain at least one of water vapor and hydrogen.
