What is Natural Red Oxide?
Red oxide is chemically called iron oxide Red . Its molecular formulas is Fe2O3. It is red in color and Lusterless. Red Oxide powder is most widely occurring in nature. It is the basic mineral for steel plant. Red Oxide has tremendous application in building, construction, paint and many other industries.
In India, good quality with high percentage of iron oxide is available in several regions. For paint, Ceramic, and building materials shade and tone of Red Oxide is important. The best shade is of course PG Red Oxide from Iran. Red Oxide is known for its corrosion protection, inertness to alkali and chemicals. Durability of paint made with Red Oxide is very well known.
