摘要:

AbstractA new method for cast‐loading of explosive charges is described. Up to now cooling was used to solidify the melt of the explosive. In this method the state of the explosive is changed by applying pressure which causes an immediate rise of the melting point according to Clausius‐Clapeyron's equation. The total melt solidifies immediately and uniformly. The method has the advantage that voids are avoided and short loading times are obtained if the melting point is raised in this manner to the temperature momentarily present in the explos

摘要:

AbstractThis paper presents an analysis of the relationship between oxygen balance, inert content, computed detonation parameters and incendivity for several water‐gel explosives. A mathematical technique has been developed for correlating compositional details and the permissibility test result for a number of existing compositions. The analysis covers two types of explosive compositions and three categories of permissibility tests. Using energy of detonation, oxygen balance and percentages of water and sodium chloride in the composition, this technique is able to consistently predict the permissibility test result with less than 10% exceptions. It is felt that this method will facilitate the design of new explosive formulations which have a high probability of success in permissibility test

摘要:

AbstractExpansion of TATB is studied on a molecular level by means of x‐ray crystallography. Continuous monitoring of the cell constants of TATB between 214 K and 377 K allows calculation of a volume change of +5.1% for this molecular system. Expansion of the pure material is almost exclusively a function of a 4% linear increase in the c axis (the perpendicular distance between sheets of hydrogen‐bonded TATB). Calculated from these data, the volume coefficient of thermal expansion for crystalline TATB is 30.4 × 10−5K−1. The structural features of crystalline TATB and its anisotropic thermal‐expansion behaviour are compared with those of graphite and boron nitride. Two other crystalline products in the bulk TATB are either actual polymorphs of TATB or

摘要:

AbstractA rapid method for simultaneous determinations of nitroguanidine and nitrate ion in the spent sulfuric acid has been developed. This method consists of merely diluting an aliquot of sample with water and measuring the absorbances of nitroguanidine and nitrate ion at 265 nm and 203 nm, respectively. In the concentration ranges studied, average accuracies of better than 1% and 2% were obtained for nitroguanidine and nitrate ion, respectively. The precision was better than 1% in both cases.
