Nickel Iron Oxide
This material is a magnetic material with some anomalous properties. This material is used as transformer core material, as a precursor in magnetic fluids, for magneting coating and many other applications. This material is entirely different from Zinc iron oxide and cadmium iron oxide. Nickel iron oxide is not antiferromagnetic. Magnetic ordering is very fine in Nickel iron oxide. Some of the methods of production of nickel iron oxide is given below:
1. Ceramic solid method: Here Nickel oxide and alpha iron oxide powders are mixed for several hours using acetone as medium. Keep the mixed powder in an hot oven at 500 Kelvin temperature for 24 hours. Again mix the powder for several hours without acetone. Now heat the powder to 1000 Kelvin temperature using a good high temperature furnace. Now the sample is ready.
2. Liquid method: Nickel sulphate and ferrous sulphate pure materials dissolved in distilled water. This solution is treated with sodium hydroxide solution until pH of the solution becomes 11. Now the solution is heated to 450 Kelvin and cooled. While cooling some ferric nitrate crystals are added to the solution. Again heat the solution until solution becomes orange red in colour. Cool the solution and filter to obtain nickel iron oxide.
Properties of Nickel iron oxide
This is almost a nanomaterial from the X-ray diffraction data of sample 1(by ceramic method) and 2 (by liquid method)
