Ceramic pigments obtained from mixtures of chromophore metal oxides and catalyst additives, providing stable colors for ceramic building materials
Description auto translated : Ceramic pigments. They are obtained starting from mixtures of powders of chromophore metal oxides (such as Feo, Fe2O3, Cr2o3, COO, Zno, Tio2, Mno2, Nio, Cuo, Zro2) with catalyst additives (sodium salts, potassium), which following a thermal treatment (calcination at 1000-1400 ° C) carried out in rolling or ovens muffola, react with solid state chemical reactions generating solid crystalline structures, stable at temperatures above 1250 ° C. These reaction products appropriately ground and mixed with nail polishes, swallows or ceramic doughs, give the ceramic building stable colors both thermally and chemically.
They can be supplied in powder in big bags or bags or in liquid form mixed only with water.
Original Description: Pigmenti ceramici. Si ottengono a partire da miscele di polveri di ossidi metallici cromofori (quali ad esempio FeO ,Fe2O3 ,Cr2O3 ,CoO ,ZnO ,TiO2,MnO2, NiO, CuO ,ZrO2) con additivi catalizzatori (sali di sodio,potassio), che in seguito ad un trattamento termico (calcinazione a 1000-1400°C) effettuato in forni rotativi o in forni a muffola, reagiscono con reazioni chimiche allo stato solido generando strutture cristalline solide, stabili a temperature superiori ai 1250°C. Questi prodotti di reazione opportunamente macinati e mescolati a smalti, ingobbi od impasti ceramici, conferiscono al manufatto ceramico colorazioni stabili sia termicamente che chimicamente.
Si possono fornire in polvere in big bag o sacchetti oppure in forma liquida impastati solo con acqua.
