Ultra-Fine Nickel Powder (Nickel Powder)
Ultra-fine nickel powder with a sharp particle size distribution and excellent crystallinity
Our ultra-fine nickel powder lineup includes submicron (< 1 μm) nickel powder.
The nickel powder is produced with the vapor-phase reduction method, in which nickel chloride is vaporized and reduced with hydrogen. Our proprietary vapor-phase reduction reaction technology makes it possible to produce nickel powder with a small particle size distribution width without using a sorting process such as classification.
Since the particle size of nickel powder is determined by adjusting the conditions of the vapor-phase reduction reaction, it is possible to produce submicron nickel powder of any desired particle size, in addition to those in our product lineup.
Purposes of use
Our nickel powder is used as the ultra-thin electrode materials for multi-layer ceramic capacitors (MLCCs).
Taking advantage of the small particle size distribution width that distinguishes our nickel powder, it is used in the electrodes of high-end MLCCs.
