Abstract This research discusses synthesizing and characterizing hexaferrite/Molybdenum disul9ide (Ba 0.6 Sr 0.4 Fe 11.75 Al 0.25 O 19 /MoS 2 ) composite materials. The Ba hexaferrite sample was synthesized using a solid-state reaction method sintered at high temperatures. Hexaferrite/Molybdenum with weight ratio of 1:9 mixed milling. Using an X-ray diffractometer (XRD), the characterization results produced samples had hexagonal structure MoS monoclinic structure. surface morphology from...
In the contrary to other common AFe 2 O 4 ferrites, Barium Monoferrite (BaFe ) have a bit more complex structure which exhibits orthorhombic structure. This permits substitute Ba 2+ with another divalent ion metals such as Strontium (Sr improve magnetic and microwave absorbing property. this study, in form of (1-x) Sr (x) Fe (0.0 x 0.5) has been successfully fabricated using high energy milling technique. Fine nanoparticle powder was characterized by X-ray diffractometer, Raman...
Neodymium substituted yttrium iron garnet (YIG) nanoparticles with compositional variation of Nd x Y 3−x Fe 5 O 12 where = 0.0, 0.2, 0.5 and 0.8 was prepared by mechanochemicals method using high energy milling (HEM). The characterization done X-rays diffractometer (XRD), scanning electron microscope (SEM), vibrating sample magnetometer (VSM) vector network analyzer (VNA). It found that the mechanical followed sintering promotes complete structural formation structure. XRD patterns confirm...
A research to study the microwave absorption properties of manganese ferrite in X-band range have been conducted by using high energy milling technique. The synthesis (Mn1+xFe2-xO4) was performed solid state reaction method with material composition (x)MnO : (2-x) Fe2O3 (x = 0.25; 0.50; 0.75 and 1.0) according molar ratio. This powder mixture being milled for 10 hours then sintered at 1200 °C temperature 3 hours. Material characterization done FTIR spectroscopy (Fourier Transform Infra Red...
Nickel ferrite doped by neodymium in the form of (Ni(1-x)NdxFe2O4) with (x = 0.0 ; 0.2 and 0.4) have been synthesized using solid state reaction method milling technique from NiO, Nd2O3 Fe2O3 powder. The mixture those compound materials was milled High Energy Milling (HEM) machine for 10 hours then sintered at 1000 °C 5 h. X-ray diffraction patterns showed that a single phase spinel has formed all compositions. result morphological observation Scanning Electron Microscope (SEM) exhibited...
Unlike other AFe2O4 ferrite materials, Barium Monoferrite (BaFe2O4) have an orthorhombic structure which is very interesting to further study the crystal and phase formation. In this study, Strontium substituted in form of Ba(1-x)Sr(x)Fe2O4 has successfully been synthesized through solid state reaction method includes BaCO3, SrCO3, Fe2O3 as starting materials. was made by varying dopant composition (Sr2+) from x = 0, 0.1, 0.3, 0.5. Each assisted ethanol continued milling process for 5 hours...
