PRODUCTION OF PALLADIUM POWDER

摘要

PURPOSE:To produce palladium powder as starting material for palladium paste used for forming an internal electrode of a laminated ceramic capacitor especially as powder less liable to expansion and shrinkage at the time of firing. CONSTITUTION:An aq. soln. of a palladium-ammonium complex salt adjusted to <=pH3 is mixed with an aq. soln. of a hydrazine compd. adjusted to <=pH3 at <=50 deg.C and the resulting mixture is heated to >=50 deg.C to deposit palladium powder.
