Nanosized (10-70 nm) Al₂O₃ doped with manganese ions (Mn³⁺) was obtained by combustion method. It was found that the resulting powder consists of a mixture of transition aluminas (δ*, δ, θ), among which δ*-phase is dominant. It was shown that a part of Mn ions exists in the oxidation state +2 and oc...
