Abstract

Nano-crystalline Ni_1.0Co_0.2Mn_1.8O ₄ powders were synthesized via non-crystalloid precursor method. The results on the precursor by XRD and IR techniques show that the stable non-crystalloid precursor could be formed by adding oleic acide and adjusting the pH values. The dried precursor exhibited auto-catalytic combustion behavior. After being calcined at 800 Ti, the Ni_1.0Co_0.2Mn _1.8O₄ powders with spinel structure were obtained. It has been demonstrated that the synthesized powder is well dispersed and with higher sintering activity. The Model of non-crystalloid precursor has been suggested. The reaction mechanism has also been proposed.
