Abstract

EL PRESENTE INVENTO SE REFIERE A UN PROCESO PARA PRODUCIR PARTICULAS DE OXIDO DE TITANIO Y PARA PRODUCIR UNA PELICULA DE REVESTIMIENTO DE OXIDO DE TITANIO. LAS PARTICULAS DE OXIDO DE TITANIO SE PRODUCEN SOMETIENDO UNA SUSPENSION DE PARTICULAS FINAS DE OXIDO DE TITANIO A UN TRATAMIENTO HIDROTERMICO A 100 O MAS, EN UN PH DE UN VALOR DETERMINADO, PARA CONSEGUIR LA CRISTALIZACION DE LAS PARTICULAS FINAS. LA PELICULA DE REVESTIMIENTO DE OXIDO DE TITANIO SE PRODUCE POR SUSPENSION DE LAS PARTICULAS ASI CONSEGUIDAS EN AGUA, AJUSTANDO LA SUSPENSION A UN PH DE UN VALOR ESPECIFICO, REVISTIENDO UN SOPORTE CON DICHA SUSPENSION Y CALENTANDOLA DESPUES PARA PERMITIR A LAS PARTICULAS DE OXIDO DE TITANIO ADHERIRSE FIRMEMENTE AL SOPORTE. LAS PARTICULAS DE OXIDO DE TITANIO Y LA PELICULA DE REVESTIMIENTO OBTENIDA DE ACUERDO CON EL PRESENTE INVENTO, SE EMPLEAN COMO PIGMENTOS, ABSORBENTES DE ULTRAVIOLETA, RELLENOS, MATERIALES OPTICOS, MATERIALES ELECTRONICOS, MATERIALES DE TRANSDUCCION OPTOELECTRICA, MATERIALES DECORATIVOS, CATALIZADORES, FOTOCATALIZADORES, PORTADORES DE CATALIZADOR, ABSORBENTES Y BIORREACTORES.
