The Effect of Copper Electrode and HSS Type Electrode on DC Thermal Plasma Methode on the Characteristics of the Nanoparticle Al2O3

Abstract

The manufacturing of Al2O3 nanoparticle using a DC plasma methode. The materials used are aluminum powder with dimensions of 88 µm. The electrode used are copper and HSS. The nano-powder Al2O3 obtained are tested using a Scanning Electron Microscopy (SEM), energy dispersive X-ray (EDX) and X-ray-diffraction (XRD). The results of the test of alumina nano-particles showed that the copper electrode has a spherical nano-particle and there is agglomeration with a size of 24.08 nm. With a purity of 96.68%. The HSS electrode produced nano-particles as 20.8nm in size, with a purity of 88.68%.
