Ignition and Combustion Characteristics of B/NC/CuO Thermite Microparticles

To improve the combustion stability and ignition performance of thermite, B/NC/CuO micro particles were prepared from boron (B), nano copper oxide (CuO), nitrocellulose (NC) as an energetic binder through electrospray technique. The burning rate dependency on content, ambient temperature, pressure was estimated by compressing into columns. Scanning electron microscopy results show that sizes these mostly lie in range 3–4 ?m. are ignitable burn consistently with minor variations conditions: B content (8.3–17%), temperature (?50–55 °C), (0.02–0.1 MPa). optimum formula observed for 11 wt% content. Compared ball milling sample, standard deviation electrosprayed sample reduced 32%. Combustion is barely affected pressure. Between ?50 °C to 55 °C, increases 14.16% initial 13.35 mm?s?1. In addition, laser energy required microparticles also 70 45 mJ.
