Abstract

The application of self-propagating high-temperature synthesis (SHS) and mechanically stimulated self-propagating reactions (MSR) in the processes involved in the processing of geological materials is described. The outlooks of MSR are connected with the possibility to perform several processes simultaneously in a mechanochemical reactor: grinding and activation of the initial and final products, and the combustion of the thermite mixture of solids. Another rapidly developing direction is that connected with the use of geological materials (minerals, ores, concentrates and technogenic waste products) as one of the components of a thermite mixture, both for the treatment of mineral raw by means of SHS or MSR resulting in semi-products (metals and alloys, ceramics and glasses) and for express analysis of natural samples for ecological purposes. Some results of the investigations are considered.
