Ni0.4Cu0.2Zn0.4TbxFe2-xO4 nanospinel ferrites: Ultrasonic synthesis and physical properties

X-Ray and Infrared Studies for NiSiXFe2-xO4 Ferrites

A spinel ferrite of the system NiSixFe2-xO4 with (x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5) were studied via IR, Xray spectra and cation distribution. The X-ray pattern confirmed the spinel cubic structure of all Si contents. The lattice parameters estimated as a function of Si contents indicated a slight decrease of lattice parameter up to 0.2. The grain size increases with increasing Si content up t...

determination of some physical and mechanical properties red bean

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...

General Properties and Applications of Ferrites

Synthesis and Characterization of Mixed Ferrites

In this work we prepare nanocrystalline mixed ferrites by equilibrated low entropy routes with generic formula of MnxNi1-xFe2O4. Two series of samples have been prepared where “x” varies as 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5 the samples have been prepared by chemical co-precipitation route. For the first calculated amount of salts of Mn, Fe and Ni were dissolved in deionized water and stirred for ...

Synthesis and Structural Characterization of Nanomanganese Ferrites

The semiconductor spinel ferrite will have the chemical formula as AB2O4 (where A  divalent metal ion like Ni, Mn, Zn, etc and B  Iron metal ion Fe2 + and Fe3 +) and many studies have focused on the synthesis of nanomaterials because of extensive applications due to their novel properties. Magnetite and spinel ferrite nanocrystals are regarded as two of the most important inorganic nanomateri...
