6b-Nitrohexahydro-2H-1,3,5-trioxacyclopenta[cd]-pentalene-2,4,6-triyltrinitrate (NHTPN) is an energetic compound with interesting properties. Its thermal and kinetic behaviors were studied by differential scanning calorimetry (DSC), and its specific heat capacity (C-p) was determined by a continuous C-p mode of microcalorimetry (Micro-DSC III). In order to evaluate its thermal safety, the values (T-e0 and T-p0) of Te and Tp corresponding to beta -> 0, critical temperature of thermal explosion (T-be and T-bp), adiabatic time-to-explosion (t(TIad)), 50% drop height (H-50) of impact sensitivity, critical temperature of hot-spot initiation (Tcr),thermal sensitivity probability density function [S(T)] vs. temperature (T) relation curves for NHTPN with radius of 1 m surrounded with ambient of 340 K, the peak temperature corresponding to the maximum value of S(T) vs. T relation curve (T-S((T) max)), safety degree (SD) and critical ambient temperature (T-acr) of thermal explosion of NHTPN were calculated respectively, by means of the onset temperature (T-e) and maximum peak temperature (T-p) from the non-isothermal DSC curves of NHTPN at different heating rates (b), the apparent activation energy (EK and EO) and pre-exponential constant (A(K)) of thermal decomposition reaction obtained by Kissinger's method and Ozawa's method, C-p, density (rho) and thermal conductivity (lambda), the decomposition heat (Q(d), taking half-explosion heat), Zhang-Hu-Xie-Li's formula, Smith's equation, Friedman's formula, Bruckman-Guillet's formula, Frank-Kamenetskii formula and Wang-Du's formulas.
