Spinels, iron titanium brown

Spinels, iron titanium brown is an inorganic pigment that is the reaction product of high temperature calcination in which iron (II) oxide and titanium (IV) oxide in varying amounts are homogeneously and ionically interdiffused to form a crystalline matrix of inverse spinel. Its composition may include any one or a combination of the modifiers Al2O3, Fe2O3, MnO, or ZnO.
