Specific Heat Capacity,Thermodynamic Properties and Adiabatic Time-to-Explosion of NTO

The specific heat capacity of NTO was determined with continuous Cp mode of microcalorimeter(Micro-DSCⅢ).In the determining temperature range from 283K to 353K,the special heat capacity of NTO presents good linear relation with temperature,the relationship between the specific heat capacity of NTO and the thermodynamic temperature was Cp=0.2806+2.7103×10-3T,the standard mole specific heat capacity of NTO was 141.53J/mol/K in 298.15K.Using the determined relationship of Cp with temperature T,thermodynamic functions(enthalpy,entropy and Gibbs free energy) of NTO between 283K and 353K,relative to the standard temperature 298.15K,were derived through thermodynamic relationship.Using the relationship between Cp and T and the thermal decomposition parameters,the time of the thermal decomposition from initialization to thermal explosion(adiabatic time-to-explosion) was obtained,which is between 1.95s and 1.99s.
