The development and implementation of nanotechnology is one of the key areas of global technological progress, comparable in value to computer science and communications, or biotechnology. Progress in electronics, medicine, materials science, mechanics, mechanical engineering, and the space industry largely depends on the development of nanotechnologies and the creation of new materials on their basis. The peculiarity of the present moment is that nanotechnologies from the sphere of research have entered the technological market and are the most dynamically developing segment. Research and development on the creation of structural materials based on metals, such as nanostructured steels, alloys, ceramics, etc., are among the priority areas of science and technology in all leading countries of the world. The article discusses the optimal conditions for the synthesis of nanomaterials and the physicochemical fundamentals of nanoindustry technology, describes the characteristics of promising nanostructured materials, methods for producing carbon nanomaterials, the field of application of nanomaterials.
