Method for purification of silicon and silicon
The invention provides a method for purifying silicon which comprises a step of blowing a treating gas generated by reacting carbon ( 20, 21 ) with an oxidized gas into a molten silicon ( 8 ), as well as silicon produced by the method. Carbon ( 20, 21 ) can be held in a container ( 14 ), the oxidize...

| Zusammenfassung: | The invention provides a method for purifying silicon which comprises a step of blowing a treating gas generated by reacting carbon ( 20, 21 ) with an oxidized gas into a molten silicon ( 8 ), as well as silicon produced by the method. Carbon ( 20, 21 ) can be held in a container ( 14 ), the oxidized gas can be passed through the container ( 14 ), and the oxidized gas can contain at least one of water vapor and hydrogen. |
