Abstract

Установлено активирующее действие микроволнового излучения в процессе синтеза нанопорошков ортоферрита иттрия, допированного никелем, заключающеесяв значительном увеличении скорости процесса, снижении температуры отжига, высокой химической гомогенности синтезированных образцов. Реальная степень допирования согласно результатам локального рентгеноспектрального микроанализа оказалась несколько ниже номинальной, максимальная реальная степень допирования составляет 0.12. Средний размер частиц YFeO3 и NiхY1-хFeO3 находится в диапазоне 200–300 нм.   REFERENCES Popkov V. I., Almjasheva O. V.

正交微波合成,用镍完成。
微波辐射是由镍制成的正交微粒合成过程中激活的,这意味着大量提高过程速度,降低退火温度,合成样品的高化学同质性。根据当地x射线光谱显微分析,实际的营养水平略低于名义水平,最高的营养水平为0.12。YFeO3和nihy1 - hfeo3的平均大小在200 - 300纳米范围内。反应性Popkov V.
