[0018] Example 1
[0019] Using analytically pure cobalt sulfate and ferric nitrate as raw materials, prepare 0.5mol / L and 1mol / L solutions respectively, measure 50ml nickel sulfate solution and 50ml ferric nitrate solution, put the above two solutions into a beaker, and then Add 100ml of sodium hydroxide solution with a concentration of 2mol / L of precipitant, stir with a magnetic stirrer at room temperature for 5 minutes to make it evenly mixed, and then heat to 60℃, stir to fully react, the cobalt and iron ions in the solution It will precipitate to form a co-precipitate of cobalt hydroxide and iron hydroxide, forming a suspension. Then pour the suspension into a quartz glass container of a strong magnetic field reactor, and place the quartz glass container in a heating device under a strong magnetic field; the magnetic induction intensity of the strong magnetic field is 8T (Tesla), and the suspension is Heat treatment in a strong magnetic field for 2 hours, the heating reaction...
