Tavernier detd the following characteristics of some French proplnts calorimetric potential (potentiel calom< trique)(Refs 3 4), volume of gases(volume des gaz)(Ref 3) and temperature of explosion (temperature d explosion(Ref 4). 

Azotidrato d argento (Silver Azide—SA) o Acido d argento, AgN 3, is described in Belgrano (Ref 31, pp 449—51). Trauzl value for 2g sample 22.5cc, Detonation Velocity 5700m/sec, Temperature of Explosion 3545° Detonation Temperature 297° (Ref 31, pp 447 451). 

The following values for props of TNT are listed in Ref 31, p 241 Density (max) 1.58, Explosion Temperature 24(f, Flame Temperature at Explosion 2800°, Heat of Explosion 980kcal/kg, Detonation Velocity at d 1.5 6700m/sec, Volume of Gas at 0° 760mm 6801iters/kg, Specific Pressure 8100atm/kg,... 

Therefore, the products on the right-hand side of the water-gas equilibrium will increase as the temperature rises. If we assume that the temperature of explosion Te — 4000 K, then the value of K1 becomes 9.208. By substituting the values for Ku a, b and d into Equation 6.6 the concentration of C02 can be calculated as shown in Equation 6.7, where... 

The endotherm at 192 °C is due to the fi-d crystalline phase change, and the exotherm at 276 °C is due to the violent decomposition of HMX. Thermal pre-ignition and ignition temperatures of explosive substances can be obtained from DTA and TGA thermograms. 

The viscosity of lubricating oil is a measure of its flow characteristics. It is generally the most important controlling property for manufacture and for selection to meet a particular application. The viscosity of a mineral oil changes with temperature but not normally with high stress and shear rate (ASTM D-5275, ASTM D-5481,ASTM D-5684, IP 294), unless specihc additives that may not be shear stable are included to modify the viscosity-temperature characteristics. Explosions can also result when lubricating oil is in contact with certain metals under high shear conditions (ASTM D-3115).
