چکیده

Forsterite (Mg2SiO4) powder was synthesized using magnesium and talc with assistance of ball milling. Manganese doped forsterite was prepared at weight percentage of 0.05%, 0.1%, 0.2%, 0.5% and 1.0wt% by adding manganese oxide before ball milling. The undoped and manganese doped forsterite were sintered at temperature of 1000°C, 1100°C and 1200°C. The Vickers hardness, fracture toughness and Young’s modulus have improved when 0.2wt% of MnO2 was added in comparison with undoped forsterite. The recommended temperature to carry out the sintering process is 1100°C where improved mechanical properties were observed.

Nanocrystalline forsterite for biomedical applications: synthesis, microstructure and mechanical properties.

Forsterite (Mg2SiO4) because of its exceptionally high fracture toughness which is close to that of cortical bones has been nominated as a possible successor to calcium phosphate bioceramics. Recent in vitro studies also suggest that forsterite possesses good bioactivity and promotes osteoblast proliferation as well as adhesion. However studies on preparation and sinterability of nanocrystallin...

Synthesis and structural properties of Mn-doped ZnO/Graphene nanocomposite

Zinc oxide (ZnO) is a promising metal oxide semiconductor with various applications, especially in the photocatalytic destruction of environmental pollutants. However, this nanoparticle has some limitations, such as poor dispersion, aggregation, and a wide energy gap. As such, the doping of metal oxide semiconductor has been strongly recommended. Addition of manganese (Mn) has proven effective ...

Synthesis and evaluation of chitosan manganese-ferrite nanoparticles as MRI contrast agent

Magnetic nanoparticles are the good choice for using in MRI as the contrast agent. Iron oxide particles such as magnetite (Fe3O4) or its oxidized form maghemite (γ-Fe2O3) are the most commonly employed in biomedical applications. In this study, we synthesized and optimized the preparation of chitosan manganese-ferrite nanoparticles (CMn-Fe nps) and evaluated its ability for the mice macrophage ...

Comparison of the effect of chromium oxide and magnesium oxide on the mechanical properties and microstructure of alumina-mullite-zirconia composites

Alumina-mullite-zirconia composites were prepared by the reaction sintering method between alumina and zircon powders and the effect of two additives (chromium oxide and manganese oxide)were investigated on their properties. 2 and 4 wt% of each oxide were added to the raw material composition and after pressing, the samples were sintered at 1630°C. The results showed that chromium oxide decreas...

Structural, optical, and magnetic studies of manganese-doped zinc oxide hierarchical microspheres by self-assembly of nanoparticles

In this study, a series of manganese [Mn]-doped zinc oxide [ZnO] hierarchical microspheres [HMSs] are prepared by hydrothermal method only using zinc acetate and manganese acetate as precursors and ethylene glycol as solvent. X-ray diffraction indicates that all of the as-obtained samples including the highest Mn (7 mol%) in the crystal lattice of ZnO have a pure phase (hexagonal wurtzite struc...
