The Thermodynamic Analysis of Ni_1/2Mn_1/2(OH)₂ Prepared by Hydroxide Co-Precipitation Method

Abstract:

The thermodynamic analysis of Ni²⁺-Mn²⁺-NH₃-OH^--H₂O in co-precipitation system was carried out, and the precursor Ni_1/2Mn_1/2(OH)₂ was prepared by hydroxide co-precipitation method. The analysis showed that the best pH value of mixed solution is 11 and the ammonia concentration is 0.4 mol/L, when NaOH is precipitating agent and ammonia is chelating agent. When the pH value is 11, the SEM images confirm that the morphology of Ni_1/2Mn_1/2(OH)₂ is the best.
