Frequently Asked Questions
What is synthetic yellow iron oxide?
Synthetic yellow iron oxide (CAS 51274-00-1, CI 77492) is an iron oxide-hydroxide pigment. It is manufactured for consistent yellow coloring in paints, lacquers, varnishes, polymers, construction materials, and cosmetics.
What is yellow iron oxide used for?
It is used as a yellow colorant in paints, lacquers, and varnishes, for coloring plastics and polymer systems, in concrete and building products, and as a cosmetic colorant (CI 77492).
Can iron oxide be yellow?
Yes. The yellow form is an iron oxide-hydroxide (CAS 51274-00-1, CI 77492), distinct from red Fe2O3 (CI 77491) and black Fe3O4 (CI 77499). Color depends on the oxide phase and hydration.
What is the Colour Index and formula for yellow iron oxide?
It is indexed as CI 77492 with the iron oxide-hydroxide composition (FeOOH-type, listed formula FeH3O3) and CAS 51274-00-1. These identifiers appear on the CoA for specification matching.
Is synthetic yellow iron oxide available in bulk and how is it priced?
RawSource supplies synthetic yellow iron oxide in bulk to manufacturers. Pricing depends on grade, tint strength, and volume, so request a bulk quote with your specification along with a CoA and SDS.
