20120164055 | METHOD OF REMOVAL OF IMPURITIES FROM SILICON - A method for the purification of metallurgical grade silicon is provided, which can be used to produce high purity silicon up to and including solar grade. The process relies on alloying and controlled solidification of Si with another metal, such as copper, zinc, iron, tin, nickel and aluminum, to produce purified platelets of Si, while the impurities are trapped in a getter alloy. The Si platelets are then separated from the solidified alloy by a physical separation technique such as gravity or magnetic separation. The separated grains of Si may then be further cleaned by acid leaching. Pre-refining of metallurgical grade silicon or post-refining of the product may be performed, depending on the initial impurity content of the feedstock, to obtain Si that meets solar grade requirements. | 06-28-2012 |
