Abstract

LA INVENCION ALUDE A UN PROCESO PARA LA PRODUCCION DE BIOXIDO DE TITANIO DE PARTICULAS FINAS Y BIOXIDO DE TITANIO DE PARTICULAS FINAS. EL BIOXIDO DE TITANIO ES A LA LUZ ESENCIALMENTE TRANSPARENTE Y TAMBIEN ABSORBENTE DE LA RADIACION ULTRAVIOLETA. PARA SU PRODUCCION SE UTILIZARA DIOXIDO DE ESTAÑO EN PARTICULAS FINAS, CUYO TAMAÑO DE PARTICULA ES DE 1 HASTA 10 NM, ESENCIALMENTE ES DE 1 HASTA 4 NM, EN UNA CANTIDAD DE 0,5 HASTA 10 DE PORCENTAJE DE PESO, REFERIDO A TIO SUB 2. MEDIANTE LA ADICION DE DIOXIDO DE ESTAÑO SE AJUSTARA EL TAMAÑO CONSEGUIDO DE LA PARTICULA DEL DIOXIDO DE TITANIO. MEDIANTE UNA MALEABILIDAD DE 300 HASTA 800 GRADOS C, LAS PARTICULAS CON FORMA DE AGUJA SERAN REDONDEADAS. POR MEDIO DE UN TRATAMIENTO POSTERIOR, LAS PARTICULAS PUEDEN SER RECUBIERTAS CON CAPAS DE SUSTANCIAS INORGANICAS Y/O ORGANICAS. EL DIOXIDO DE TITANIO DE PARTES FINAS, PUEDE SER PRODUCIDO SOBRE SODIOTITANATO POR DESCOMPOSICION CON ACIDO CLORHIDRICO O MEDIANTE UNA HIDROLISIS PROPIA DE UNA COMBINACION DE TITANIOTETRAVALENTE, LA CUAL LLEVA A UNA FORMACION DE RUTILO. EL DIOXIDO DE ESTAÑO SE APLICA PREFERENTEMENTE COMO UNA SOLUCION COLOIDAL, QUE SE CONSIGUE MEDIANTE LA REACCION DEL TETRACLORURO DE ESTAÑO CON AGUA, CONFORMADA EN UN MAXIMO DE 22 GRADOS C.
