Iron Oxide Black (CAS 1317-61-9) is a synthetic inorganic pigment (Pigment Black 11). It is valued for its durability, as it does not fade under UV light or react with cement. It is the primary pigment for creating dark grey to black concrete products. In the paint industry, it is used in anti-corrosive primers and industrial coatings.
Verified listings ensure consistent jetness and tinting strength, essential for high-quality decorative concrete and construction products.

Yes, synthetic Iron Oxide Black has the same structure as natural Magnetite and is magnetic.
If heated above 180°C, it will oxidize into Iron Oxide Red (Fe2O3). However, at ambient temperatures outdoors, it is perfectly stable.
It is 'alkali-stable', meaning it won't be destroyed by the high pH of cement. This ensures the black or grey color of tiles stays permanent.
G722 is the industry standard code for high-quality synthetic Black Iron Oxide used in the construction and paver industry.
