| Abstract: |
| The influence of dopant dosage on properties of capacitor grade tantalum powder was analyzed. The physical properties, chemical components and electrical properties of tantalum powder with different dopant dosage were analyzed. The results show that under the same process conditions, with the increase of dopant content, the oxygen content of tantalum powder rises, the apparent density and Feuerbach''s particle size of tantalum powder drop, the content of -0.043 mm fine powder increases, and the leakage current, capacity and shrinkage rate have an increasing trend, and the breakdown voltage tends to decrease. |
