Plasmachemical Synthesis and Basic Properties of CoFe2O4 Magnetic Nanoparticles
Cobalt-ferrite (CoFe2O4) nanoparticles (CFNPs) are obtained using direct plasmachemical synthesis in the plasma of a low-pressure arc discharge. The formation of the CFNPs with an average size of 9 nm and a narrow granulometric ...
Synthesis of Nanosized Titanium Oxide and Nitride Through Vacuum Arc Plasma Expansion Technique
Physical vapor deposition techniques such vacuum arc plasma deposition — which are very commonly used in thin film technology — appear to hold much promise for the synthesis of nanocrystalline thin films as well as ...
Plasma-chemical synthesis of copper oxide nanoparticles in a low-pressure arc discharge
The influence of a pressure of gas mixture (10 vol% O2 + 90% N2) on an average size of copper oxide nanoparticles, produced in the plasma of low pressure arc discharge, has been studied as a basic process variable. A ...
The influence of oxygen concentration on the formation of CuO and Cu2O crystalline phases during the synthesis in the plasma of low pressure arc discharge
This paper describes the synthesis of copper oxide nanoparticles with different percentages of CuO and Cu2O phases. It was achieved by the control of the percentage of oxygen in the gas mixture (N2 + O2) in a plasma-chemical ...
Plasma-chemical Synthesis of Fe3O4 Nanoparticles for Doping of High-Temperature Superconductors
Ferrite nanoparticles (Fe3O4) have been produced by the direct low-pressure plasma-chemical synthesis. X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), vibration magnetometry (VSM), and ...
Influence of the Oxygen Concentration on the Formation of Crystalline Phases of TiO2 during the Low-Pressure Arc-Discharge Plasma Synthesis
The synthesis of titanium dioxide (TiO2) nanoparticles with different percentage of anatase and rutile phases is investigated. The synthesis is performed by controlling the oxygen percentage in the gas mixture in the ...
