The initial mixture (stoichiometric composition) was calculated according to the valences of the reactive elements, in order to favor the oxidant / fuel ratio = 1 according to the propellants chemistry [6].
The bands in the range of 600 to 400 cm-1 typically correspond to n1 and n2 stretching of the tetrahedral and octahedral sites of the crystal structure.
