摘要：
Measurements of electrical resistivity are the most available, sensitive, and informative tools for exploration of the state of the contact surface between individual particles in powder materials. Application of these methods to SHS science and technology enables one to study the oxidation of the particles’ surface, to optimize the processes of intermixing, mechanical activation, sintering, and also to shed light on other physical, chemical, and mechanical transformations taking place in powder materials. The available data of resistivity measurements have been analyzed and found to agree quite well with the chemical composition, burning velocities, mechanical properties, and surface relief characteristics of the materials under consideration.
