Synthesis of Y3Fe5O12 (YIG) assisted by high-energy ball ...

studies show that ball milling mechanically dissolves Y 2O 3 in the ferrite matrix and produce highly supersaturated matrix with Y and O solutes, which are otherwise insoluble. The decomposed Y 2O 3 is considered to re-precipitate [5] during hot consolidation in the form of nanoscale clusters and complex near stoichiometric oxides such as Y 2Ti ...

Dec 15, 2016· YFeO 3 nanopowder was synthesized via high energy ball milling and subsequent sintering.. DTA analysis indicated that most of the product (YFeO 3) has been formed at below 367 °C.. UV-Vis confirmed that considerable amounts of visible light were absorbed by YFeO 3.. YFeO 3 could not be considered as a ceramic with a good colossal dielectric constant.

Effect of mechanical milling induced strain and particle ...

A new Y−Fe alkoxide, [YFe(OPri)6(PriOH)]2, is used in the sol−gel process to obtain the orthoferrite, YFeO3. The Y/Fe stoichiometry (1:1) and Y−O(R)−Fe chemical links in the single molecular precursor kinetically control the formation of metastable YFeO3 which is otherwise difficult to prepare due to the easy formation of the garnet composition, Y3Fe5O12.

mixed in a ball mill for 3hrs with Alcohol and ZrO2 balls. The slurry was dried and then calcined at 1200oC for 2hrs in an air atmosphere furnace with a heating rate of 5oC/min. The calcined powder was re-milled by vibration mill for 2hrs. After being milled, the powder was pressed into cylindrical molds. Cold

The precursors mixed in a stoichiometric ratio to obtain YIG were milled at room temperature in a shaker mixer mill with a ball:powder weight ratio of 10:1. A partial synthesis of YIG was achieved after 9 h of milling time by using the three sources of iron; however, a significant fraction of the product was the perovskite YFeO 3 .

The powders were mixed in a ball mill and then calcined several times at 1100°C to get a homogenous single phase. This single-phase powder was then pressed into a pellet and sintered at 1150°C to get a pellet with >95% density. These sintered pellets were used for all structural and properties characterizations.

It is inferred that the Ce-doped YIG ferrites likely contain Fe 2+ ions due to the low oxygen condition during high temperature sintering. This assumption has been verified by the XPS spectra of Ce x Y 3−x Fe 5 O 12 (x = 0.2) ferrite as shown in Fig. 2.The 2p 3/2 and 2p 1/2 peaks of the Fe ion can be observed at 710.6 eV and 724.3 eV in Fig. 2(a) respectively.
