Abstract：Aiming at understanding the light radiation properties of KClO4/Zr combusting under different conditions, emission spectrum and combustion products for KClO4/Zr combusting in open air and closed quartz tubes were studied respectively. Energy distribution of the light radiation signal and the emission intensity evolution with time were measured with fiber optic spectrometer, and photo-diode and oscilloscope. Spectral efficiency within (590±10), (750±10) and (808±10) nm were analyzed respectively according to the obtained flame emission spectrum. Morphology of the combustion products of KClO4/Zr were observed with scanning electronic microscopy (SEM). Results showed that the flame emission spectrum of KClO4/Zr distributed within the visible and near infrared width wave band, whiel the strongest radiation appeared within 730 nm to 820 nm band. When burning in closed quartz tubes, detected combustion emission spectrum intensity decreased significantly with the decrease in size of the tube. Also, the energy distribution of the emission spectrum showed different variation trends, and to deal with flame emission spectrum distribution, as the change of volume of quartz tubes, (590±10), (750±10) and (808±10) nm bands’ spectral efficiency are also present different change rules. Generally, increasing the diameter of the quarts tube favored the increase of the effective light radiation energy detected outside of the tube, and decreasing the diameter of the quartz tubes favored the peak emission intensity of KClO4/Zr. With the increase of tube diameter, KClO4 burning more fully, the product particle size is smaller; the morphology is the rule of the globular. And the change of tube length is not too large effect in the reaction results.
