Abstract

LA PREPARACION DE ESTOS PIGMENTOS, A BASE DE SILICATO DE CIRCONIO COMO SUSTANCIA DE REVESTIMIENTO Y PARTICULAS DE HOLLIN COMO FASE DE INCLUSION, SE REALIZA POR CALCINACION DE UNA MEZCLA A BASE DE DIOXIDO DE CIRCONIO, UNA FUENTE DE DIOXIDO DE SILICIO, HOLLIN Y SUSTANCIAS MINERALIZANTES, EN CONDICIONES REDUCTORAS A 900 ION DE ZEOLITAS COMO FUENTE DE SIO2, CON UNA PROPORCION MOLAR DE SIO2/AL2O3 MAYOR A 4, PREFERENTEMENTE MAYOR A 10. UTILIZANDO SIMULTANEAMENTE UN ADHERENTE, ESPECIALMENTE ACEITE DE SILICONA, PUEDE AUMENTARSE LA INTENSIDAD DEL COLOR. LA UTILIZACION DE ZEOLITAS HACE POSIBLE LA INCORPORACION DE DISTINTAS CALIDADES DE DIOXIDO DE CIRCONIO Y PERMITE LA PRODUCCION DE PIGMENTOS CON MAYOR PROPORCION DE HOLLIN INCLUIDO
