摘要：

This paper reports the sintering and electrical properties of Tantalum anodes made from the electron beam (EB) refined tantalum metal powder. Tantalum anodes were compacted from two different tantalum batch powders and sintered at different temperatures. Electrical properties such as capacitance and voltage were measured and CV values calculated. Presented results encompasses the effect of impurities, average particle size, green density, and sintering temperature, on the CV value of anodes. It was found that higher CV values could be obtained from sintering of fine powder at low temperature. (C) 2002 Elsevier Science B.V. All rights reserved.
