SILICA AND IRON OXIDE BASED PIGMENTS AND METHOD FOR THE PRODUCTION THEREOF

Pigments based on silica and iron oxide and manufacturing process thereof. In order to obtain a pigment of silica-iron oxide, microsilica is blended and/or milled with a source of iron oxide in ratios between 2 and 30 % by weight of iron oxide. With the blending of raw materials a dry agglomerate is...

More Information
Summary:Pigments based on silica and iron oxide and manufacturing process thereof. In order to obtain a pigment of silica-iron oxide, microsilica is blended and/or milled with a source of iron oxide in ratios between 2 and 30 % by weight of iron oxide. With the blending of raw materials a dry agglomerate is obtained that is calcinated at temperatures between 800 and 13001 C, obtaining a product that is milled to obtain a powder of red colour. This colorant can be used in a wide range of uses, for example, added to a standard porcelain stoneware composition, it allows red and orange coloured pieces to be obtained.
