RCF NATURAL RED OXIDE 

Ferric Oxide (Hematite Fe2O3)

General Description

Mineral pigments are coloured natural earths used in the manufacture of oil and water paints and to give colour and body to cement, linoleum, oil cloth, rubber and sundry plastic materials. Most mineral reds derive their colour from the presence of varying amounts of ferric oxide Fe2O3, the mineral hematite. This may be present in relatively small percentages, as in the red slates and shales, or it may constitute as much as 90% or more of the material. The red oxide may occur naturally or it may be produced by heating hydrous iron oxide pigments, such as yellow ochres to a sufficiently high temperature to drive off the water of composition.
