Abstract

El objeto de la presente invención es un proceso para la fabricación, acondicionamiento y estabilización de una familia aditivos base óxidos de sodio, potasio, boro, silicio, zinc, calcio, entre otros, preparados por métodos fisicoquímicos y de síntesis química que forman estructuras nanométricas, reformulados con aditivos defloculantes, secuestrantes y dispersantes que permiten obtener una dispersión o polvo con la capacidad de disminuir la temperatura de sinterizado de un cuerpo cerámico por su alto poder de fundencia, que se maximiza por el uso de la nanotecnología en las estructuras obtenidas, el proceso consiste en la preparación de semillas de nucleación de óxidos metálicos, silicatos y carbonatos mediante un proceso fisicoquímico, y los cuales permiten crecer mediante un proceso químico estructuras de índole nanométrico en un proceso de síntesis química en vía húmeda de óxidos de sodio, boro, silicio, zinc, potasio y calcio. La combinación de estos óxidos permite estructurar elementos de alto poder fundente por su alta área superficial y su composición fisicoquímica. Los aditivos elaborados en la presente invención se estabilizan químicamente con agentes defloculantes, que permiten a los aditivos ser incorporados en el proceso de molienda en medio acuoso del cuerpo cerámico. Las aplicaciones elaboradas con los aditivos de la presente invención permiten disminuir la temperatura de sinterizado de un cuerpo rojo desde 1150°C hasta 1000°C y en cuerpos porcelánicos gres de 1180°C a 1050°C, con el uso de 0.2 a 5 % del aditivo, o bien incrementando la velocidad del tratamiento térmico hasta en un 20%, pudiendo ser utilizado en la fabricación de sanitarios, piezas de moldeo, componentes para herramientas, revestimientos, cenefas, esmaltes, engobes y otros componentes cerámicos. La presente invención propone varias formulaciones de aditivos nanoestructurados con propiedades fundentes de alto desempeño, que permiten optimizar y uniformizar el proceso de sinterizado y mejorar las propiedades mecánicas del cuerpo cerámico. Así mismo propone diferentes métodos de aplicación del aditivo de formulaciones cerámicas.
