Manufacture of Iron Oxide Pigments - Chempedia - LookChem

Red iron oxide pigments are mainly obtained by roasting and calcining processes. α-Fe 2 O 3 is obtained by oxidative calcination of all decomposable iron compounds. Decomposition of iron sulfate and α-FeOOH and the oxidation of Fe 3 O 4 are industrially important. After prior dehydration to the monohydrate, ferrous sulfate heptahydrate is oxidatively roasted at temperatures above 650°C ...
