Abstract

Se describe un método para fabricar productos porosos que consisten esencialmente en subóxidos de titanio de la fórmula general TiOx, en donde el valor de x se encuentra entre 1.6 y 1.9, dicho método comprende las siguientes etapas: a) mezclar las materias primas que comprenden al menos una fuente de dióxido de titanio, un agente reductor que comprende carbono, b) conformar el producto, c) opcionalmente, en particular cuando se utilizan productos orgánicos durante la etapa a), el tratamiento térmico al aire o en una atmósfera oxidante, d) sinterizar, por ejemplo, a una temperatura superior a 1150 ºC pero que no exceda los 1430 ºC, en una atmósfera neutra o reductora. en donde la fuente de dióxido de titanio consiste en al menos 55% en peso de anatasa. Producto obtenible mediante dicho método.
