2. 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.

   In 1973, Albright & Wilson's chrome business was bought and renamed British Chrome & Chemicals [24] and substantial investment was made in the production of chromic oxide. A complementary business was bought in the US in 1979 and renamed American Chrome & Chemicals, making Durham a world leader in chrome and iron oxide pigments.

4. Ceramic colorants - Wikipedia

   en.wikipedia.org/wiki/Ceramic_colorants

   Red iron oxide is commonly used to produce earthy reds and browns. It is the metal responsible for making earthenwares red. Iron is also another tricky colorant because of its ability to yield different colors under different circumstances. At low percentages (.5-1%) and in the presence of potassium, iron will become light blue or light blue ...

   Iron oxide pigment. The brown color indicates that iron is at the oxidation state +3. Green and reddish brown stains on a limestone core sample, respectively corresponding to oxides/hydroxides of Fe 2+ and Fe 3+. Iron oxides feature as ferrous or ferric or both. They adopt octahedral or tetrahedral coordination geometry. Only a few oxides are ...

9. Iron(III) oxide - Wikipedia

   en.wikipedia.org/wiki/Iron(III)_oxide

   Iron(III) oxide is a product of the oxidation of iron. It can be prepared in the laboratory by electrolyzing a solution of sodium bicarbonate, an inert electrolyte, with an iron anode: 4 Fe + 3 O 2 + 2 H 2 O → 4 FeO(OH) The resulting hydrated iron(III) oxide, written here as FeO(OH), dehydrates around 200 °C. [18] [19] 2 FeO(OH) → Fe 2 O 3 ...
