Abstract
METODO DE REFINO DE SI. A presente invenção refere-se a um método de refino de Si de baixa pureza por meio de uma escória, em particular removendo B, que suprime desgaste do recipiente de reação devido à escória e produz Si de alta pureza usado para materiais de baterias solares, etc. a baixo custo, compreendendo esse método adicionar SiO~ 2~ e um óxido alcalino ou carbonato alcalino como material de escória a Si fundido para formar a escória, durante o que se adiciona um ou mais tipos de materiais entre os mesmos ingredientes do material do recipiente de reação utilizado ou ingredientes incluídos no material do recipiente de reação para a escória, de modo a remover as impurezas no Si fundido.
