| Abstract: |
| The Spark Discharge method in inert gas, due to simplicity, no need for complex equipment and raw materials, the ability to produce high-purity nanoparticles and mix metallic nanoparticles, susceptible method for synthesizing nanoparticles for narrow size distribution is considered. This method is capable to produce nanoparticles of electrical conductor materials such as semiconductors. Also, with small changes in Spark Discharge system, can capable to deposit thin layer. Now this method has been used for producing carbon, metal, alloy and metal oxide nanoparticles. Primary objective of this study was to construct high voltage electrical discharge in the gas system. Next step is synthesis NiTi alloy nanoparticles in this way in Argon, using the same Ni-50at%Ti alloy as electrodes. Characterization of NiTi nanparticles by FESEM, DLS, EDX, XRD and HRTEM help to determine the NiTi nanoparticles size distribution, morphology and composition. The results showed the primary nanoparticles size ranging 10 nm to 20 nm with the composition which is closed to that one of the electrodes used to obtain them. |
