At the large and powerful industrial (private or state) enterprises of the world, particularly, Kazakhstan, RF, and some other post-Soviet (and not only) countries, the products are manufactured using obsolete technologies with high wastes’ generation. At that, the storage and warehousing are unorganized and technically unreasonable (wastes of different chemical compositions and hazard class are mixed) that does not allow their further efficient recycling. Increased processing of many industrial and household wastes is not only economical, but also considerably improves the environmental situation, significantly reduces the consumption of natural raw materials, and reduces the use of scarce lands for waste storage . The authors of this article carried out a literary review on this topic and attempted to use microsilica, as a waste of silicon production, to create new materials with special properties. This refers to the field of experimental study of structures, phases, structural components for understanding the processes of alloying, modification, diffusion, etc. Understanding physical thinking from the metal physics point of view in the study of the nature and kinetics of the phase transformations, alloying, and modification processes enables using the physical research methods to solve research and technological problems in metallurgy and materials science in order to predict and change the required set of properties. The method of research in this article is electron microscopy as the simplest and fastest method of obtaining information about the microstructure, elemental composition, and distribution of components in the bulk.
Keywords: alloying, microalloying, modification, modifier, alloying element, production waste.
