以粉煤灰为原料，采用共沉淀法合成了纳米铁酸镍粉体。X射线衍射分析表明，纯的结晶镍铁氧体NiFe，04相可以通过在所研究的pH范围（从7（中性）到12（高碱性））中在>800 ° C的温度下热处理前体120分钟来获得。在500摄氏度的温度范围内
Nano-sized nickel ferrite powders have been synthesized from fly ash via a chemical synthesis route, co-precipitation method. X-ray diffraction analyses showed that pure crystalline nickel ferrite, NiFe,04, phase can be obtained by thermal treatment of the precursors at temperature >800 degrees C for 120 min in the studied pH range, from 7 (neutral) to 12 (highly alkaline). In the temperature range of 500 degrees C
