The results of the studies on the synthesis of ultrafine copper powders are described in the article. The mechanisms of formation of ultrafine powders, using water-soluble polyacrylamide and polyvinyl-pyrrolidone polymers, as particle growth inhibitors, are presented. The processes occurring in the presence of water-soluble polymers and their influence on the structure of the obtained ultrafine copper powders are described. The interaction of the matrix of polymer composite materials with filler particles is analyzed. The kinetics of crystallization and transformation of crystalline phases of the powder, due to the process in the presence of water-soluble polymers, as stabilizers of particle growth, are investigated.

“…Furthermore, this material can be combined with other ceramic systems such as aluminum oxide (Al 2 O 3 ), silicon nitride (Si 3 N 4 ), and silicon carbide (SiC) for the fabrication of structural components used in high temperature, erosive, and/or corrosive applications. [1][2][3][4][5][6][7][8] TiC powders can be synthesized by direct reaction between titanium and carbon, carbothermal reduction of titanium oxide sources, gas phase reaction, selfpropagating high-temperature synthesis (SHS), sol gel, spark erosion, microwave heating, laser chemical vapor deposition, and so on which have drawbacks though, such as the formation of a coarse sintered structure, formation of a non-stoichiometric composition, need for initial raw materials of high purity, and need for post-milling. Furthermore, each method has varying characteristics of particle size and distribution, morphology, state of agglomeration, chemical purity, and stoichiometry.…”

In this research, the effect of heating on the mechanical alloying process for synthesizing of titanium carbide was investigated. Raw materials containing pure titanium and graphite powders were milled in different times and temperature. In order to detect phases and properties of synthesized materials X-ray diffraction was applied. Physical properties including density and specific surface area along with microstructure were studied. Results showed that heating can accelerate the mechanical alloying process. By increasing the temperature during milling, production mechanism of titanium carbide changed from self-propagating high-temperature synthesis to gradual model. Changes of density confirmed this phenomenon too. Increasing the milling time leads to particle size and crystal of synthesized titanium carbides became finer down to nanometer scale. Because of higher effective time span of produced titanium carbide, increasing the temperature produces finer particle sizes of powders in similar milling time.
