SUBLIMATION
STUDIES
Mass loss of a HME at different
temperatures. This information is used to
evaluate the thermal stability of the
material, the heat of sublimation and
estimate time of residence on a surface.
TATP + TNT

Thermal decomposition of a mixture of TATP and AN.
The decomposition of TATP is shifted to higher temperature suggesting
decomposition or desensitization.
