Abstract (en)

[origin: WO9322255A1] The invention concerns a sintered-ceramic material, for high-stability thermistors, of the general formula: MgzNiMn2-zO4, where 0 < z < 1, produced by converting a thermally unstable nickel manganese oxide spinel system, such as NiMn2O4, into a thermodynamically stable compound of the composition MgNiMnO4 by the substitution of manganese by magnesium.
