Mechanochemical treatment, specific features of the structure and properties, and reactivity of SHS systems based on natural materials. 1. Mechanochemical synthesis of disperse nanostructured composite quartz-based systems
Abstract
This paper presents the results of experimental investigations of the dispersion of quartz particles with their simultaneous modification in a planetary-centrifugal dynamic mill depending on the variation of the time-force regimes of mechanochemical treatment. Nitrogen- and carbon-containing compounds were used as modifiers. The laws of change in the dispersivity, imperfection, and transformation of the surface layer structure and the morphological features of synthesized particles of the composite polymer/mineral structure in the process of mechanochemical treatment have been established. We have shown the relationship between the mechanical action and the piezoelectric response of the system to the process of modification of the newly formed surface of quartz particles and their capsulization into hetero-organic shells, whose composition and structure are determined by both the quality of the material-base and the kind of the modifier.
