Аннотация: Rare-earth ferrite garnets (REFGs) have pronounced magnetic and optical properties and are widely used in magnetooptics, laser and microwave technologies. This work offers a method for producing Yb3Fe5O12 powders with a mean grain size of 47 +/- 9 nm, by means of the anion-exchange resin coprecipitation of iron(III) and ytterbium fПоказать полностьюollowed by annealing of the product at 1100 degrees C. The anion-exchange resin precipitation rate and optimal parameters have been determined, as well as the parameters of precursors heat treatment. The products have been characterized by chemical analysis, X-ray powder diffraction, differential scanning calorimetry, and electron microscopy. The method is promising for the production of other REFGs and nonferrous metal ferrites.

This work offers a method for producing Yb3Fe5O12 powders with a mean grain size of 47 ± 9 nm, by means of the anion-exchange resin coprecipitation of iron(III) and ytterbium followed by annealing of the product at 1100°C. The anion-exchange resin precipitation rate and optimal parameters have been determined, as well as the parameters of precursors heat treatment.
