Synthetic red oxide of iron
Synthetic Iron Red Oxide Pigment/powder (Ferric Oxide) has been formulated by varied chemical reactions using Synthetic Oxides of Iron. The Iron red oxide available with us is of excellent qualities like Light Fast, Acid Resistant, Permanent Stable Color, and Brightness & Heat Stable. The unique red color is due to the inorganic compounds present in the basic iron, and it is inert in nature.
