Abstract： A method for the determination of silver content in conductive silver paste was reported in this paper. The effect on the testing results of silver content with the sample carrier, roasting temperature, dosage of lead foil, and puffing temperature was studied. The results indicated that after weighing of samples using lead foil, roasting at 250 ℃,15 g of lead-package, cupellation at 900 ℃ were a comparatively ideal analytical scheme. Silver with the equivalent amount of silver in the sample was weighed and then tested according to the determination procedure and environmental condition. The recovery rate of silver was taken as correction factor k to correct the analysis results.The recoveries of silver in samples ranged from 99.6% to 100.2%.The found values were consistentwith recommended values, the relative standard deviation (RSD) were 0.51% and 0.71 % (n=5).
