It was found that the Frank-Kamenetskii model, combined with kinetic data from differential scanning calorimetry, gave the best agreement with the experimental results. However, careful selection of the kinetic parameters proved critical and, in this study, DSC data provided more relevant predictions than ARC data. By appropriate selection of size and geometry, the models could be further applied to predict self-ignition temperatures for other mixtures and geometries or systems that can be related to actual fireworks.<\/p>\n<p align=\"left\"><strong>Keywords:<\/strong> sulfur, chlorate, fireworks, thermal stability, self-heating, Frank-Kamenetskii, Thomas<\/p>\n<hr \/>\n<p><strong>Ref:<\/strong> JPyro, Issue 18, 2003, pp53-62<br \/> (J18_53)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>J.
