CONDUCTIVE MICROPARTICLES FOR FORMING AN ELECTRODE, METAL PASTE, AND ELECTRODE

WIPO Patent Application WO/2012/008373

A1

Disclosed are: conductive microparticles for manufacturing a metal paste that can be used to manufacture a low-resistance electrode film; and a metal paste using said conductive microparticles. The disclosed conductive microparticles for forming an electrode have a core/shell structure comprising: core particles that comprise platinum or a platinum alloy and have diameters of 10-200 nm; and shells that comprise a ceramic containing Al2O3 or ZrO2 and cover at least parts of the core particles. The weight of the ceramic constituting the shells is 0.5-15% of the weight of the core particles. The core particles are preferably either platinum or a platinum alloy alloyed with palladium/gold/silver/rhodium.
