Specific Heat of Octahydro - 1,3,5,7 - Tetranitro - 1,3,5,7 - Tetrazocine (HMX).

Abstract

The specific heat of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) has been studied with a Differential Scanning Calorimeter from 315-486 degrees K. Measurements were made on both small pieces of single crystals of HMX and on a powdered blend. In both cases, the specific heats of the beta and alpha phases, and also of partially decomposed HMX were determined. The results show that the specific heat values for the two phases are nearly the same. Differences in the specific heat values for the single crystals, powdered and partially decomposed samples are small, and all lie within a bond of 6%. The value for the single crystals are the lowest; for the powdered blend, intermediate and for the partially decomposed; highest. In the case of the single crystals versus the powder, the values are within the combined experimental error of 3%. (Author)
