Determination of Zr oxidation level from the ZrO signal in LIBS according to moisture-induced ageing. (a) Detection of the ZrO molecular signal for non-aged and aged samples. Here, the non-aged samples were prepared by varying the value of x in Table 3 from 0 to 0.8. (b) Construction of a calibration curve from AUC results. (c) Determination of the oxidation level of Zr upon ageing. These results indicate that exposure to moisture is fatal to the fuel component in a pyrotechnic delay material.
