Applications to Vapor-pressure Determination

Adonyi (50) developed a method in which the Derivatograph could be used for vapor-pressure determinations. The method is similar to that discussed by Ashcroft (48). 

Probably the most important characteristic of military and commercial explosives and solid rocket propellants is performance as related to end use and safety. Performance can be described by a variety of conventional properties such as thermal stability, shock sensitivity, friction sensitivity, explosive power, burning, or detonation rate, and so on. Thermal analysis methods, according to Maycock (51), show great promise for providing information on both these conventional properties and other parameters of explosive and propellant systems. The thermal properties have been determined mainly by TG and DTA techniques and isothermal or adiabatic constant-volume decomposition. Physical processes in pseudostable ma- 

The correct interpretation of the large amount of experimental data obtained by these techniques is a problem not to be taken lightly, since many important decisions relative to the use of a particular material may be based on these interpretations. It is obvious that these techniques can be used both for quality control and as an approach to the basic science of pseudostable materials. 

TG and other TA techniques and their applications to cements and alloys have been reviewed by Baker (134). Gal et al. (135) described how the Deriva-ato graph can be used to investigate the complex system of dust The uses of TG and other TA techniques to archaeometry has been discussed by Bayer and Wiedemann (136). 

Pyrotechnic compositions containing KC103 and lactose have been studied by TG and other TA techniques by Scanes (137). Oxidation of the lactose by the KC103 may be represented by the equation
