Abstract
Nickel powder batches and methods for producing nickel powder batches. The powder batches include particles having a small particle size, narrow size distribution and a spherical morphology. The present invention is also directed to devices incorporating the nickel metal powders.
Claims6
A powder batch comprising metal composite particles, wherein said composite particles have a weight average particle size of not greater than 5 μm and a particle size distribution wherein at least 90 weight percent of said particles are not larger than twice said average particle size, and wherein said particles include a metal phase comprising nickel metal and at least a first non-metallic phase dispersed throughout said metal phase wherein said first non-metallic phase is a dielectric compound selected from the group consisting of titanates, zirconates, silicates, aluminates, tantalates and niobates.
A powder batch comprising metal composite particles, said composite particles having a weight average particle size of not greater than 5 μm, wherein said composite particles include a metal phase and at least a first non-metallic phase dispersed throughout said metal composite particles said non-metallic phase comprising a ceramic dielectric compound selected from the group consisting of titanates, zirconates, silicates, aluminates, tantalates and niobates.
