Embodiment 1
[0035] Step 1: Take ferrous ammonium sulfate, cobalt nitrate, copper nitrate, zinc acetate, nickel sulfate and Mix urea, then add it to the high-speed centrifugal dispersion tank, disperse the material in the high-speed centrifugal dispersion tank at a speed of 1500r / min for 30min, and take it out to obtain mixture A;
[0036] Step 2: Put the mixture A in a high-temperature tube furnace, and rapidly raise the temperature from room temperature to 140 °C at a rate of 15 °C / min in a flowing argon atmosphere of 100 sccm, keep it warm for 1 hour, and cool it naturally to room temperature after the heat preservation is over. After taking out, obtain product B;
[0037] Step 3: Grind the product B with a mortar for 20 minutes, then put the ground solid powder into a freeze-drying box, and let it stand at a low temperature of -10°C for 6 hours;
[0038] Step 4: Take the above product out and put it into a high-temperature tube furnace. In a flowing argon atmosphere of 100 sccm, rapid...
