Thermal Analysis Curves of Energetic Materials

Energetic materials exist in a substable state under normal conditions. In order to estimate their properties and potential danger, it is important to establish their thermal characteristics and thermal behavior, The thermal analysis curve is one of the important bases for obtaining information in this field. 

In this chapter, about 70 thermal analysis curves for 60 samples are presented. Most of these curves were measured by the author with an LCT thermal analyzer equipped with a laboratory-made 4.1 model thermal analyzer (constructed at the Beijing Optical Instrument Factory) and a Shimadzu DSC-50 instrument. Other curves were obtained from the literature. 

The conditions for the measurements with the LCT model were as follows micro sample holder with a PtRhlO-Pt thermocouple and quartz sheath normal sample mass 2-3 mg heating rate 10°Cmin DTA sensitivity 25 gV (total deflection) TG range 10 mg (total deflection) temperature measurement range 10 mV paper speed of recorder 4 mm min platinum crucible (diameter 5 mm, height 3 mm, open type) reference crucible empty and temperature of the free end of thermocouples for temperature measurement was 0 °C. A TWT-464 electronic potentio-metric recorder made by the Shanghai Second Automatic Instrument and Meter Factory was used for recording data. KNO, In, KCIO4 etc., were used to calibrate the temperatures, and a 

The conditions for measurements using the Shimadzu DSC-50 instrument were as follows sample mass about 1.0 mg heating rate 10 °C min nitrogen atmosphere (purity 99.99%) flow-rate 20 ml min platinum crucible (diameter 5 mm, height 3 mm). In, Sn, Zn, Al, KCIO4, etc., were used as standard samples for temperature calibration. 

A Mcttler II thermal analyzer was used in the work by Krien cited throughout this chapter. Other measurement conditions were as follows heating rate 6°Cmin DTA sensitivity 100 mV (total deflection) PtRh-Pt thermocouples used to measure the temperature, range 2 gV (full-scale) aluminum crucible, open reference material -Al20v dynamic dry air, flow-rate ca 97 ml min (5.8 1 h ).
