2. Lead (II,IV) oxide - Wikipedia

   en.wikipedia.org/wiki/Lead(II,IV)_oxide

   Lead(II,IV) oxide, also called red lead or minium, is the inorganic compound with the formula Pb 3 O 4. A bright red or orange solid, it is used as pigment, in the manufacture of batteries, and rustproof primer paints. It is an example of a mixed valence compound, being composed of both Pb(II) and Pb(IV) in the ratio of two to one. [2]

   4, "chrome yellow"), lead(II,IV) oxide, (Pb 3 O 4, "red lead"), and lead(II) carbonate (PbCO 3, "white lead") are the most common forms. [1] Lead is added to paint to accelerate drying, increase durability, maintain a fresh appearance, and resist moisture that causes corrosion. It is one of the main health and environmental hazards associated ...

5. Iron oxide red - Wikipedia

   en.wikipedia.org/wiki/Iron_oxide_red

   Iron oxide pigments in jars: yellow, red, brown. Iron oxide red is a generic name of a ferric oxide pigment of reddish colors. Multiple shades based on both anhydrous Fe 2 O 3 and its hydrates were known to painters since prehistory. The pigments were originally obtained from natural sources, since the 20th century they are mostly synthetic.

6. Rust converter - Wikipedia

   en.wikipedia.org/wiki/Rust_converter

   A common example is phosphoric acid, which additionally converts some iron oxide into an inert layer of ferric phosphate. [3] Most of the rust converters contain special additives. [4] They support the rust transformation and improve the wetting of the surface. Applied rust converter
