“…Their size is determined by the competition between thermolysis and sintering. A decrease in the probability of sintering can be attained by a fast decomposition of salts at the high temperatures followed by cooling of the products formed [30].…”

“…Such materials are called "cluspol" [30,[63][64][65], and for their production it is necessary to provide the most possible melt temperature, which must be considerably above the temperature of the carbonyl decay initiation. For this purpose the carbonyl dilute solutions are used under these conditions, providing the ultimately fast and complete removal of the split out ligand from the reaction system.…”

The processes of thermal decomposition play an important role in various practical fields including metallurgy, mineral conversion processes, pyrogenic chemical technology, pyrolysis and thermal treatment of wood and coal, combustion of natural and synthetical fuels, coal carbonization, the prevention of grain spontaneous ignition, and so on. There is still a need for scientifically well-founded approaches to control the thermal decomposition of materials. Many studies focus attention on the chemical transformations and reactions in the pyrolized systems and on the creation of mathematical models of such processes as the major parts of the theory of chemical decomposition of complex substances.Thermolysis is widely used in the synthesis of nano-sized metallopolymer composites. This is a result of the specifics of the preparation of such materials. In spite of a variety of the methods for the preparation of metallopolymer nanocomposites, there are two principal routes: "bottom-up" and "top-down."

IntroductionThe various physical and mechanical parameters of metallopolymeric nanocomposites can be considerably improved with retention or sometimes even with the increase in the conventional magnetic characteristics (saturation magnetization, coercive force, etc.) that show considerable promise for various applications. Such substances are very perspective as high-density information media, materials for permanent magnets, magnetic cooling systems, or fabrication of magnetic sensors. They can also be used for medical and biological applications, e.g., for magnetic resonance tomography, magnetic targeted drug delivery systems, magnetic resonance imaging (MRI) contrast enhancement, color imaging, and cell sorting [1,2].Ferromagnetic metal particles can be formed in a polymer matrix (ferroplastics or ferroelastics) by practically all methods for synthesis of metal nanoparticles in polymers. The manufacturing method can be subdivided into three large groups: physical, chemical, and physicochemical. The division is very conventional and is based mostly on the method of nanoparticle formation and the character of their interactions with the matrix. The first group of methods includes the procedures seemingly devoid of any chemical interactions between the dispersed phase and the dispersion medium. Composites of this type are rare. More popular chemical methods of manufacturing nanocomposites are based on interactions between components anticipated or detected. The reduction reactions and precursors are well known. Nevertheless, the new approaches have been elaborated from practical demands and many details of the chemical reduction are still unclear. The third group of methods are those when metal or their oxide nanoparticles are formed using high-energy processes of atomic metal evaporation, including low-temperature discharge plasma, radiolysis, and photolysis in the presence of monomer and polymer. Recently, such methods have become widely used in vacuum metallization Magnetic Nanoparticles. Sergey P. Gubin

Synthesis of Powder Materials with Particles Encapsulated into Carbon Containing Nanostructural Films

Particles of a complex structure: a quartz nucleus encapsulated into metalpolymer carbon containing nanosize film of the type "cluspol" have been obtained as a result of mechanochemical treatment of quartz with carbon containing organic compounds. Electronmicroscopic investigations show the diversity of morphological forms and nanostructural carbon formations on the surface of modified quartz particles. Depending on the regimes of mechanochemical treatment, the obtained materials are characterized by considerable changes in electromagnetic properties. The choice of carbon containing modifiers provided a highly active physico-chemical state of quartz of a prolonged action.
