Description

The thermal decomposition of the important pyrotechnic composition BLC 190 (boron:red lead, 10:90) has been studied by isothermal and nonisothermal differential scanning calorimetry (aluminium sample pans, nitrogen atmosphere). The decomposition has been found to proceed at temperatures around 700 K through a first-order reaction obeying a simple Arrhenius law with an activation energy 434 kj/per mole, pre-exponential log10A/(pers) = 29.7 and heat of reaction 846 J/per g. No change in weight was observed in the reaction mixture, before and after heating and the end-product is a lead borate salt, Lead diborate or lead tetraborate rather than boric oxide. The reaction pathway appears to have a kinetic step similar to that of BPBO (boron: PbO, 10:90). Keywords: Pyrotechnics, Lead compounds, Boron compounds.
