Abstract
A noble metal and solid-phase lubricant composition and an an electrically conductive interconductor including the electrically conductive composition are disclosed. The electrically conductive composition includes a noble metal component and a solid-phase lubricant component. The solid-phase lubricant component is present in an amount sufficient to cause the electrically conductive composition to have a coefficient of friction which is significantly lower than the coefficient of friction of the noble metal component without causing the electrically conductive composition to be significantly less malleable than the noble metal component, nor to be significantly less corrosion resistant than the noble metal component. The electrically conductive composition can form a contact layer of the electrically conductive interconnector. The contact layer is bonded to a diffusion barrier which, in turn, is bonded to a bulk electrical conductor of the electrically conductive interconnector.
