Abstract
A theoretical and experimental study of the stored energy of detonation synthesis nanodiamonds (DND) has been conducted. It has been proven that DNDs have excess energy compared to natural and synthetic diamonds. Possible sources of excess energy are considered. Based on the data on thermogravimetric analysis of DND samples obtained under various synthesis conditions, the results of analysis of the stored energy of the samples are presented as a function of the specific surface area of the particles. It was found that the larger the surface of the particles, the more heat is spent on its production and released during combustion. The electrostatic charge of the particle surface, acquired by them in a corona discharge, has been studied. It is shown that the property to acquire an electrostatic charge by DND powders is associated with the effect of stored energy.
