Composición de esmalte cerámico fotocatalítico
Composición de esmalte cerámico caracterizada por que comprende, en porcentaje en peso respecto al peso total de la composición: a) de un 50 a un 90 % en peso de un producto que a su vez comprende de un 10 a un 90 % en peso de un compuesto con propiedades fotocatalíticas y de un 10 a un 90 % en peso de al menos un material natural y/o sintético seleccionado de un grupo de sustancias con estructura de feldespato o feldespatoide; b) de un 5 a un 50 % en peso de al menos un aditivo fundente; c) e un 0,5 a un 20 % en peso de tripolifosfato sódico.
The present invention relates to a ceramic glaze composition characterized in that it comprises, in percentage by weight in relation to the total weight of the composition: a) from 50 to 90% by weight of a product, which in turn comprises from 10 to 90% by weight of a compound with photocatalytic properties, and from 10 to 90% by weight of at least one natural and/or synthetic material selected from a group of substances with feldspar of feldsparoid structure; b) from 5 to 50% by weight of at least one fluxing additive; and c) from 0.5 to 20% by weight of sodium tripolyphosphate. It will be also an object of this invention the method for preparing said ceramic glaze, as well as its application in ceramic pieces capable of reducing NOxs existing in the air. The compound with photocatalytic properties may be TiO 2 in the form of anatase, SrTiO 3 , KTaO 3 , ZrO 2 , ZnS,CdSe,GaP, SiC. The fluxing additive may comprise in wt% 30-80 PbO, 15-70 SiO 2 , 1-10 ZnO, 1-8 Na 2 O, 0.5-6 TiO 2 , 0.2-6 Al 2 O 3 .
