Abstract
PURPOSE:To produce titled powder having excellent uniform coating property and high temp. stability by adding ammonium dihydrogen citrate to an. aq. silver nitrate soln. and further adding hydrazine and heat-treating the resultant silver coated powder. CONSTITUTION:Ammonium dihydrogen citrate is added to an aq. silver nitrate son. at about 0.85kg per kg of silver nitrate, thence core powder is added. Then, hydrazine or its salt, for example, hydrazine sulfate, is added and after this is dissolved, aq. ammonia soln. is added to control pH to >=9, whereby silver coated powder is formed. Next, this silver coated powder is washed and dried, after which it is heat-treated in hydrogen or an inert gas, whereby the silver coated powder for conductive fillers having excellent uniform coating property and high temp. stability is obtained.
