水热法制备尖晶石型镍铁氧体

Preparation of Nickel Ferrite Spinel by Hydrothermal Method

采用水热法制备尖晶石型镍铁氧体,研究了反应温度、反应时间对产品的影响,在p H=9,230℃,4 h时制得的Ni Fe2O4的晶形最好,XRD衍射峰最强,形貌最佳和比饱和磁化强度最大。

Nickel ferrite spinel was prepared by hydrothermal method. Effects of reaction temperature and time on the product were studied. The results show that optimized conditions are as follows： reaction temperature 230 ℃, time 4 h, p H = 9; crystal shape of nickel ferrite spinel prepared under above conditions is the best, XRD peaks are the strongest, saturated magnetization is the largest, and the morphology is the best.
