[ 1 ] - THE EFFECT OF DY- DOPING ON THE STRUCTURAL AND MAGNETIC PROPERTIES OF MN-ZN FERRITE NANOPARTICLES
Mn0.8Zn0.2Fe2-xDyxO4 (where x= 0, 0.025, 0.05, 0.075, 0.1) ferrite nanoparticles were synthesized by auto- combustion sol-gel method for the first time in this study. The effect of Dy-doping on the structural and magnetic properties of the produced specimens was examined using the X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometery (VSM), and ...
[ 2 ] - Effect of fluoride additive on alpha-Alumina Formation from Active Alumina
a-Al2O3 is the most important raw material for synthesizing modern ceramics and high alumina refractories. Active Alumina (also known as Hydratable Alumina and r-Al2O3) is a kind of transition alumina which is produced by flash-calcining of Gibbsite at 500-600 oC. In this research, the effect of Ammonium bi-fluoride additive (NH4HF2), on the formation of a-Al2O3 from active alumina was investig...
