| titleOfInvention | Silicon purification method |
| abstract | Silicon and slag containing P as impurities are heated to melt each, and silicon and slag are brought into contact in a molten state so that P in silicon is absorbed by the slag, and then these are cooled and solidified. By performing the second step of pulverizing the obtained silicon and treating it with an aqueous solution containing an inorganic acid after performing the first step of separating and removing the slag having absorbed P from silicon at least once. A silicon purification method for removing P contained in silicon, wherein the composition of slag contains at least one basic oxide, and the basic oxide, neutral oxide, acidic oxide, alkali In the case of a mixture selected from a metal halide and an alkaline earth metal halide and containing an acidic oxide, the content of the acidic oxide is less than the content of the basic oxide. Method for purifying silicon which is the composition. [Effects] P in silicon can be efficiently removed at a lower cost than the conventional purification method. [Selection figure] None |
