Abstract
Samples of magnetite, prepared by standard methods for obtaining of melted ammonia synthesis catalysts have been studied. The samples contain small amounts of additives, such as K2O (0.4–1 mass%), CaO (0.7–1.5 mass%), Al2O3 (0–2 mass%), WO3 (0–1 mass%) and MoO3 (0–0.6 mass%). Some influences of the additives to magnetite, as well as formation of other individual phases were established.
