Abstract:
The present invention relates to a method for obtaining optical interference effects on enamelled or non-enamelled ceramic or glass surfaces or enamelled metallic surfaces by means of the digital ink-jet technique. Said method involves applying "ink-jet effect inks" with a high refraction index on a laminar interphase with a sub-micrometric particle size with a low refraction index. The invention additionally comprises a ceramic, glass or metallic product decorated by means of said method.
Abstract:
The present invention is directed to a composition of raw material which, after melting, provides a mixture comprising: between 2 and 7 % w/w of Na 2 O+K 2 O, wherein the amount of K 2 O is at least double the amount of Na 2 O measured by weight; between 10 and 22 % w/w of MgO+CaO; between 4 and 12 % w/w of Al 2 O 3 ; between 50 and 65 % w/w of SiO 2 ; and between 4 and 10 % w/w of TiO 2 ; characterized in that it comprises less than 8% w/w of B 2 O 3 ; less than 3% w/w of ZnO; less than 2% w/w of BaO; less than 2% w/w of PbO; less than 2% w/w of SrO; and less than 1% w/w of Li 2 O. The present invention is also directed to a frit, enamel and ceramic component comprising the same.

Abstract:
Producto vítreo de liberación controlada caracterizado porque comprende óxido de boro (III) y al menos un óxido de un metal de transición seleccionado de entre hierro, manganeso, zinc, cobre, molibdeno y sus mezclas. El procedimiento para su obtención se caracteriza porque comprende mezclar los componentes, fundir dicha mezcla a una temperatura que varía de 800 a 1500°C, enfriar la mezcla fundida para que solidifique, triturar la mezcla fundida y solidificada y, opcionalmente, incorporar el producto vítreo obtenido a un soporte. La liberación de los componentes del vidrio por la acción del agua u otros factores, es controlada por el diseño de su composición y proceso productivo, convirtiéndolo en idóneo para su uso como fertilizante en agricultura.
