In the production of tantalum capacitors (TC), there is a crucial component of the design without which the process is impossible – a sintered tantalum pellet with a tantalum wire lead. This lead can be inserted into the pellet during pressing and then sintered or welded to the already sintered pellet.

In tantalum capacitor manufacturing, there is a steam pyrolysis process where tantalum pellets are decomposed by steam. Humidity control in this process is important to maintain product quality and improve yield.
Tantalum capacitors have come a long way in recent years, so much so that besides the anode material, they don''t really share much in common with their legacy counterparts. In this webinar, KEMET''s Samuel Accardo (Field Application Engineer) explains just how far tantalum capacitor technology has come and the applications in …
This study focuses on testing the effects of one and several reflow processes on surface mount tantalum capacitor characteristics, especially in a humid environment. …
Recovery of Ta from Ta-capacitors is presented following two different recovery routes using alkaline and acidic leaching. • A complete silica-free tantalum-rich concentrate is generated in the pre-processing stage. • The formation of insoluble potassium tantalate in ...
Tantalum Capacitors are electrolytic capacitors that use a material called tantalum for the electrodes. Large values of capacitance similar to aluminum electrolytic capacitors can be obtained. Also, tantalum capacitors are superior to aluminum electrolytic capacitors in temperature and frequency characteristics.
Due to the large capacitance density, wide operating temperature range and excellent frequency characteristics, tantalum electrolytic capacitors are an essential passive …

Tantalum is a critical metal that is widely used in electronic products. The demand for tantalum is increasing, but the supply is limited. As tantalum waste products have increased in Taiwan in recent years, the treatment of spent tantalum capacitors has become necessary and important. The recycling of tantalum from tantalum capacitors …
Global anthropogenic tantalum cycles have been developed for the years 1970–2015. • Tantalum''s EoL-RR seems to have declined from a high of 25% in the 1990s to 18% today. • Only 21–25% of tantalum produced since 1970 is …
Tantalum is widely used in electronic devices and is crucial for modern society; however, research on the tantalum flow in China was very limited and the scientific evidence for formulating targeted policies was insufficient. Stock and flow of tantalum in China were analyzed here, with its entire life cycle from 2011 to 2019, to reveal the key …
