Magnetic susceptibilities of chromites from Oman
MINERALOGICAL and physical characteristics of natural chromites from Oman ophiolites have been recently investigated using M6ssbauer spectrocopy (MS), X-ray diffraction (XRD) and Scanning electron microscopy (SEM) by Al-Alawi et al. (1996). From the MS analysis together with the SEM data, they derived the chemical formula for specimens collected from two separate chromite deposits named Tawiyah...
متن کاملMagnetic Properties of Cobalt Ferrite synthesized by Hydrothermal and Co-precipitation Methods: A Comparative Study
The magnetic properties of calcined cobalt ferrite formed by nano-crystalline powders have been compared by two different methods (co-precipitation and hydrothermal). The structural properties of the produced powders were investigated by X-ray Diffraction (XRD), scanning electron microscopy (SEM). The results show that the formation of cobalt ferrite spinel structures is effected by changing me...
متن کاملSynthesis of cobalt ferrite nanoparticles using a combination of the co-precipitation and hydrothermal methods
In this work we have examined the influence of the pH on the structural and magnetic properties of cobalt ferrite (CoFe2O4) nanoparticles obtained by a combination of the co-precipitation and hydrothermal methods. The crystal structures and the particle sizes of the prepared powders were analyzed by the X-ray diffraction and transmission electron microscopy, while the magnetic properties of the...
متن کاملHydrothermal Preparation and Characterization of Ultralong Strontium-Substituted Hydroxyapatite Whiskers Using Acetamide as Homogeneous Precipitation Reagent
The ultralong strontium- (Sr-) substituted hydroxyapatite (SrHAp) whiskers were successfully prepared using acetamide as homogeneous precipitation reagent. The effect of the Sr substitution amount on the lattice constants and proliferation of human osteoblast cells (MG-63) was further investigated. The results showed that the SrHAp whiskers with diameter of 0.2-12 μm and ultralong length up to ...
