SOLVATOTHERMOLYSIS AS A METHOD FOR MODIFICATION OF PYROTECHNICAL COMPOSITION COMPONENTS
A new method for modifying the components of pyrotechnic compositions has been developed. The use of the solvatothermolysis of bis(N, N'-dinitromere)ammonium cuprate as a method for modifying the components of pyrotechnic compositions with nanosized copper (II) oxide is considered. In the course of solvatothermolysis, the formation of particles of nanosized copper (II) oxide is observed on the surface of the modified substances, the number of which increases depending on the reaction time. The dependence of the yield of nanosized copper (II) oxide on the reaction time has been established. It was found that with an increase in the reaction time, the amount of modifier on the surface of the components of pyrotechnic compositions increases, and reaches a value of more than 98.6% at a 6-hour reaction. Experimental studies of KClO<sub>4</sub>/Ti and KNO<sub>3</sub>/B pyrotechnic compositions with modified components have been carried out. Comparative tests with pyrotechnic compositions prepared by mechanical mixing containing the same amount of n-CuO in their recipe showed that the burning rate of the latter is higher than that of modified pyrotechnic compositions by 0.179 mm/s for KClO<sub>4</sub>/Ti and 0.476 mm/s for KNO<sub>3</sub>/B.
