Abstract.
Nowadays studying the kinetics of chemical reactions is very important for
solving problems of detonation physics, growth of hi-tech structures, etc. With
using the high precise THz spectroscopy the kinetics of thermal decomposing the
high energy materials (by the example of ammonium nitrate) and detecting the
decomposition products both at room temperature and at heating in linear and
isothermic modes as well as staging of decomposition processes have been
studied. The absorption lines of ammonium, nitrous oxide and nitric acid have
been registered. The yield time and yield temperature of the decomposition
products as well as the number of reaction have been determined. The
prospective of using the high precise THz spectroscopy for studying the
kinetics of thermal decomposing the high energy substances, determining the
process staging and developing the reliable kinetic models has been shown.
Key words:
terahertz frequency range, high precise non-stationary spectroscopy, high
energy substances, kinetics of thermal decomposition, ammonium nitrate.
