Preparation of YIG fine particles by mist pyrolysis

Yttrium iron garnet single crystal fine particles were synthesized by mist pyrolysis from an aqueous solution of yttrium and iron nitrates dissolved in distilled water. Mist was generated by an ultrasonic nebulizer operated at 1 MHz. Thermal decomposition was carried out by passing through the mist...

Beschreibung
Zusammenfassung:	Yttrium iron garnet single crystal fine particles were synthesized by mist pyrolysis from an aqueous solution of yttrium and iron nitrates dissolved in distilled water. Mist was generated by an ultrasonic nebulizer operated at 1 MHz. Thermal decomposition was carried out by passing through the mist in a reaction tube kept a temperature at 800 °C. As-collected particles were spherical, but still amorphous. Fine YIG particles with the average diameter of 0.25 μm were obtained by calcination at 1000 °C for 20 min.
