Hydrothermal synthesis and characterizations of Ti substituted Mn-ferrites

Structural and magnetic properties of cadmium substituted manganese ferrites prepared by hydrothermal route

“…These results are consistent with the results obtained for the lattice parameters, where increasing the lattice parameter may results in increase in the total crystallite sizes. Similar results were reported for other spinel ferrites [13] and PZT ferroelectric materials [21,[40][41].…”

“…Various methods [10][11][12][13][14][15][16] such as mechanical milling, inert gas condensation, hydrothermal reaction, oxidative precipitation, sol-gel synthesis and reverse micelle technique are employed for the preparation of ferrites nanoparticles. It was reported that at elevated temperatures (200-1000 1C), MnFe 2 O 4 was unstable in air and Mn 2 þ ions on the surface oxidize to form Mn 3 þ ions resulting in the dissociation of the ferrites [17].…”

“…Therefore preparation methods involving calcination steps are not suitable for the preparation of manganese ferrite nanoparticles. On the other hand, ferrites were prepared via the hydrothermal method at temperatures ranging from 150 to 200 1C without the need of high processing temperature or calcination steps [13]. In recent years, commercial interest in hydrothermal synthesis has been revived [18].…”

Cathodic activation of synthesized highly defective monoclinic hydroxyl‐functionalizedZrO2nanoparticles for efficient electrochemical production of hydrogen in alkaline media

“…[34][35][36][37] One of the inclusively used methods for the production of various oxide nanostructures is the hydrothermal method. [38][39][40][41] In recent years, hydrothermal processing at an industrial scale has been revived. The central advantage of this processing route is that, the shape, size, crystallinity, and homogeneity of the produced powders can be controlled by regulating the reaction conditions such as temperature, time, solvent, surfactant, and precursor characteristics.…”

Low-Temperature Synthesis of Nanocrystalline Mn<sub>0.2</sub>Ni<sub>0.8</sub>Fe2O<sub>4</sub> by Oxalate Precursor Route

“…These include chemical inhomogeneity, coarser particle size and introduction of impurities during ball milling. Various soft chemical methods [23][24][25][26][27][28][29] like mechanical milling, inert gas condensation, hydrothermal reaction, oxidative precipitation, sol-gel synthesis and reverse micelle technique are employed for the preparation of nanoferrites. Most of these methods are economically unfeasible for large scale production.…”
