Abstract
EL PRESENTE INVENTO TRATA DE UN PROCESO DE PREPARACION DE BORUROS DE TIERRAS RARAS. LA CARACTERISTICA DEL PROCESO ES CALENTAR UN HALOGENURO DE TIERRA RARA, DE ALUMINIO Y DE BORO ELEMENTAL. POR HALOGENURO SE ENTIENDE PREFERENTEMENTE, UN CLORURO O UN FLUORURO DE TIERRA RARA. COMO BORURO DE TIERRA RARA SE OBTIENE UN HEXABORURO O UN TETRABORURO DE TIERRA RARA SEGUN LAS CANTIDADES STOECOMETRICAS APLICADAS.
