Abstract
Powder properties and sintering behavior of Ni powders for multilayer ceramic capacitors (MLCCs) have been studied. It is shown that the Ni powders prepared by chemical vapour deposition (CVD) have high dispersibility, compactibility, and crystallinity. Sintering behavior of the Ni powders have been different from those prepared by liquid-phase reduction method (LRM). This is well explained by the particle size distribution. Use of fine Ni powder prepared by CVD has enabled to make thin and plain inner electrodes. We have developed new MLCCs with high reliability by using CVD Ni-powders.
