Frequently Asked Questions
What is synthetic black iron oxide used for?
Synthetic black iron oxide (CAS 12227-89-3, CI 77499) is an iron-oxide pigment used as a black colorant in paints and coatings, plastics, construction materials, and cosmetics. It also serves as a functional filler and adsorbent.
Which iron oxide is black?
The black iron oxide is magnetite, Fe3O4, indexed as CI 77499 (CAS 12227-89-3). This differs from red Fe2O3 (CI 77491) and yellow iron oxide-hydroxide (CI 77492).
What is the chemical formula and Colour Index for black iron oxide?
Synthetic black iron oxide is Fe3O4 (magnetite) with Colour Index CI 77499 and CAS 12227-89-3. These identifiers are listed on the CoA for specification matching.
Why choose synthetic over natural black iron oxide?
Synthetic grades are manufactured for consistent particle size, tint strength, and purity batch to batch, which natural mined oxides vary on. Consult the CoA for the specific grade's assay and particle data.
Is synthetic black iron oxide available in bulk and how is it priced?
RawSource supplies synthetic black iron oxide in bulk to manufacturers. Pricing depends on grade and order volume, so request a bulk quote with your target quantity along with a CoA and SDS.
