Colors: Red Oxide / Black Oxide / Yellow Oxide / WhiteOxide / Grey Oxide

Colour oxides are used for giving necessary colors to tiles. The requirement will vary according to the color selection. Normal requirement is about 1000 grams for 100 kg of cement. Iron oxides are chemical compounds composed of iron and oxygen. All together, there are sixteen known iron oxides and oxyhydroxides. Iron oxides and oxide-hydroxides are widespread in nature, play an important role in many geological and biological processes, and are widely used by humans, e.g., as iron ores, pigments, catalysts, in thermite and hemoglobin. Common rust is a form of iron (III) oxide. Iron oxides are widely used as inexpensive, durable pigments in paints, coatings and colored concretes. Colors commonly available are in the "earthy" end of the yellow/orange/red/brown/black range.
