Iron Oxides - Golchha Pigments In the Laux Process Iron Oxides are obtained as a by-product of the aniline process. The main pigment obtained is Black Iron Oxide, partially also Yellow Iron Oxide. These pigments are sold directly or used for preparation of Red Iron Oxide in the Calcination Process.

Stainless Steel Passivation - Pureflow The key is to have a uniform chromium oxide film with an acceptable chrome to iron ratio (typically >1) and thickness (20-50) angstroms. Passivation is required to or enhance the chromium oxide film on the stainless steel surface when it has been manipulated by surface finishing, welding, grinding, external contamination, etc.

Why Passivate Stainless Steel and What Happens If You Don’t grinding, external contamination, etc. Mechanical finishing of stainless steel surfaces allows for a very smooth surface and is a prerequisite for sub-sequent electro-polishing. The mechanical action disrupts the existing passive surface and results in a surface with a low chrome to iron ratio.

Iron Oxide Black - Digitalfire Synthetic black iron is fluffier and lighter than synthetic red iron oxide (a bag of black iron is much larger than a bag of red). It is a very fine powder, 100% will easily wash through a 325 mesh screen. Synthetic black iron does not agglomerate as badly as red iron, thus it disperses in glaze slurries better (thus avoiding fired speckle).
