Article Description

Ferrites with the components ratio typical of hexaferrite prepared by co-precipitation and calcined at 700–1000 °C were characterized by different methods. It has been shown that hexaferrite phase formed at 700 °C is amorphous and its crystallization occurs at 800 °C. Specific surface area of the samples calcined at 700 °C is 27–59 m 2 /g. Temperatureprogrammed reduction of the samples with H 2 proceeds in several steps, Fe(III) in the sample being partially reduced to Fe 0. The main components on sample surface are in oxidized state: Fe 3+ and Mn 3+. Among the samples concerned SrMn x Fe 12-x O 19 (0 ≤ x ≤ 2) are the most active catalysts in methane oxidation.
