NICKEL POWDER FOR USE AS ELECTRODES IN BASE METAL ELECTRODE MULTILAYERED CERAMIC CAPACITORS

摘要

Nickel powders, particularly powders for use as an electrode material, with oxidised surfaces. The nickel/nickel oxide powders are micron sized. The surface oxygen of the nickel powder is NiO, in an amount corresponding to 0,5-5 mg per m2 or 2-20 molecular surface layers. The powders are produced by a transferred arc plasma process and the oxide is created on the freshly formed particles from nickel vapour when these are still entrained in the carrier gas.
