Preparation and characterization of magnesium/teflon/viton mixtures for tracking flares

Abstract

This article examines the influence of fuel/oxidizer ratios and particle sizes of the fuel on combustion characteristics of the pyrolant based on magnesium, polytetrafluoroethylene, and Viton such as heat of explosion, the specific volume of gaseous products, burning rate, and IR intensity. Based on the theoretical and experimental analysis, an appropri-ate ingredient and particle sizes of components were chosen to meet the requirement for tracking flares. The pyrolant has a medium autoignition temperature and a low sensitivity to friction. It means that the pyrolant is quite safe in transportation, storage, and use.
