Effect of Nano-CuO on Luminous Intensity of Pyrotechnics Composite Containing KClO₄ and Al

Abstract:

Nano-CuO had been successfully synthesized by using direct precipitation method. The prepared sample was characterized by XRD. The luminous intensities of pyrotechnics composite containing KClO₄, Mg and nano-CuO were measured. The catalysis of CuO nanocrystal on KClO₄ was investigated by thermal analysis instrument. The results show that the average size of nano-CuO is 19 nm and has spherical-shape. When nano-CuO is added into the pyrotechnics composites containing KClO₄ and Al, it can improve the igniting and burning performance. The luminous intensity of trinary pyrotechnics composite is also greatly increased. On the other hand, nano-CuO can make thermal decomposition temperature of KClO₄ to decrease 97.7 °C, the decalescence amount also reduced to 79.07 J/g. It is obviously that nano-CuO has strong catalysis to KClO₄ thermal decomposition. The conclusion is consistent with the measure results of luminous intensity.
