Study on nano-particles of iron nitride prepared by dielectric barrier discharge

采用介质阻挡放电的方法,以羰基铁和氨气为原料制备氮化铁纳米粒子,对生成的粒子进行XRD物相分析,并研究外加电压和反应气体比例对生成粒子粒度的影响。结果表明:羰基铁在挥发温度为0℃,外加电压为120V,通入气体比例为0.0625时,生成粒子粒径在20～70nm内,平均粒径为26nm。

The dielectric barrier discharge method was used to prepare nano-particles of iron nitride. The raw materials were iron carbonyl and ammonia.The prepared nano-particles were studied by X-ray diffraction. The influence of external voltage and ratio of reaction gases on particle size was studied. The result indicated that particle size of 20 to 70 nm,and average particle size of 26 nm was obtained on condition that volatilizing temperature was 0 ℃, external voltage was 120 V and ratio of reaction gases was 0....
