The Effect of Low Calcination Temperature on the Stability of Manganese Iron Oxide Pigments
Manganese black is a mixed oxide of manganese and iron and the pigment is stable in acids and alkalis and also at high temperatures, shows excellent lightfastness, and is compatible with all other pigments. Iron oxides can be converted by means of a solid-state reaction with manganese oxide into a substance that has far greater heat stability, namely manganese ferrite. Calcination, which is an important stage of solid state reaction, has two parameters: temperature and time. The calcination temperature causes changes in the crystallite size of the material, lattice distortion rate, and specific surface area. In this study, it is aimed to observe the changes to be obtained by decreasing the calcination temperature of Manganese Iron Oxide (MnFe2O4), which is the raw material source used in the production of black inorganic pigments.
