Abstract Hydrogen gas evolution method has been applied to determine the percentage of aluminium (Al) in hydroxy‐terminated polybutadiene (HTPB) based composite solid propellants premix/pastes. The determination is not effected by the presence of Zn, Fe, Cu or small amounts of silicon but magnesium has been found to interfere in the analysis. The results are obtained with remarkable accuracy and reproducibility.
