Abstract
"SILìCIO METALúRGICO DE PUREZA MéDIA E PROCESSO DE ELABORAçãO". A invenção refere-se a um processo de fabricação de um silício de pureza média, compreendendo: - a elaboração por redução carbotérmica da sílica no forno elétrico com arco submerso, de um silício de baixo teor em boro; - a afinação do silício líquido ao oxigênio ou ao cloro; - o tratamento do silício afinado sob pressão reduzida de 10 a 100 Pa com injeção de gás neutro; - uma solidificação segregada. Ela tem igualmente por objeto um silício de pureza média destinado a servir de matéria-prima para a fabricação de silício de qualidade eletrónica ou fotovoltáica, e apresentando (em frações mássicas): - um total de impurezas compreendido entre 100 e 400 ppm, do qual um teor em elementos metálicos compreendido entre 30 e 300 ppm; - um teor em boro de 1 a 10 ppm; - uma relação entre teor em fósforo e em boro compreendido entre 0,5 e 1,5.
