Summary: | The invention discloses a quantitative determination method for the content of AlH3 in a solid propellant. The method comprises the following steps: S1, propellant sample preparation: preparing solid propellant samples with different AlH3 contents; s2, testing: performing XRD (X-Ray Diffraction) testing on solid propellant samples with different AlH3 contents by covering an internal standard; and S3, data analysis: drawing a standard curve that the XRD characteristic peak area ratio of the AlH3/internal standard formed by solid propellant samples with different AlH3 contents changes along with the AlH3 content, and calculating the AlH3 content of the solid propellant with the AlH3 content to be detected through the standard curve. The method is used for quantitatively determining the content of AlH3, is simple and convenient to operate, and realizes component determination of a propellant sample in a lossless state.
