    • The method of obtaining ternary chemical compounds based on iron oxide and manganese oxide The subject of the invention consist of the method of obtaining ternary chemical compounds based on iron oxide and manganese oxide used in the processes of chemical oxygen transport in chemical looping during fuels combustion or gasification. The method of obtaining ternary chemical compounds based on iron oxide and manganese oxide, consisting in mixing the initial components, calcinating the mix at a high temperature, according to the invention is characterised in that powdered graphite at the amount of 1 to 2 wt.% in relation to the initial mix is added to the initial components in the form of Fe 2 O 3 and MnO 2 and an inert material, used in proportions resulting from a general chemical formula ∑( X Fe2O3 + Y MnO2 + Z inert material ) = 100 wt.%, where X and Y are within the ranges 1≤x≤99, 1≤y≤99 and the inert material is used at the amount supplementing to 100 wt.%, and the whole is subject to at least one-stage calcination in an oxidising atmosphere at a temperature of 600 –1500°C during 3 to 24 hours.
