<p>THE INVENTION PROVIDES A NICKEL-RHENIUM ALLOY POWDER THAT CONTAINS NICKEL AS A MAIN COMPONENT, 0.1 TO 10% BY WEIGHT OF RHENIUM AND 50 TO 10, 000 PPM OF SILICON IN TERMS OF SILICON ATOMS, AND THAT IS SUITABLE, IN PARTICULAR, FOR THE FORMATION OF AN INTERNAL ELECTRODE LAYER FOR A MULTILAYER CERAMIC ELECTRONIC COMPONENT. THE OBTAINED POWDER IS HOMOGENEOUSLY MIXED AND DISPERSED IN AN ORGANIC VEHICLE, TOGETHER WITH OTHER ADDITIVES AS NEEDED, TO PREPARE A CONDUCTOR PASTE. WHEN USED IN PARTICULAR FOR FORMING AN INTERNAL ELECTRODE OF A MULTILAYER CERAMIC ELECTRONIC COMPONENT, THE NICKEL?RHENIUM ALLOY POWDER OF THE INVENTION DELAYS SINTERING INITIATION AND SLOWS DOWN THE PROGRESS OF SINTERING DURING FIRING, EVEN FOR EXTREMELY FINE POWDERS, WHILE BRINGING THE SINTERING SHRINKAGE BEHAVIORS OF ELECTRODE LAYERS AND CERAMIC LAYERS CLOSER TO EACH OTHER. MOREOVER, THERE OCCURS NO ELECTRODE SPHEROIDIZING CAUSED BY OVERSINTERING. A THINNER, DENSE INTERNAL ELECTRODE HAVING EXCELLENT CONTINUITY CAN BE FORMED AS A RESULT.</p> |
