Influence of BaTiO_3 nano particle on paste and sintering properties of Ni internal electrode films by MLCC

摘要

Aming at obtaining a thinner electrode layer,Ni powder of 0.2 mum grain size was used and BaTiO_3 particles of either 30 nm or 50 nm in xize were added. The results indicate that when BaTiO_3 nanoparticles with good dispersibility are added to Ni powder of 0.2 mu,it is possible to suppress sintering of the Ni electrode paste film by adding BaTiO_3 particles. This was clarified from the results of the firing shrinkage rate and the fine structure of the sintered surface.
