a good way to tell whether a canister type is electrolytic capacitor or tantalum is to use a pair of cutters and try to cut it in half. an electrolytic capacitor will crush flat and a tantalum capacitor will barely make a dent. i have found some tantalum canister types that were as large as the big electrolytic capacitors. ill try to find a ...

Tantalum minerals with over 70 different chemical compositions have been identified. Those of greatest economic importance are tantalite, microlite,and wodginite; however, it is common practice to name any tantalum-containing mineral concentrate as 'tantalite' primarily because it will be processed for the tantalum values and is sold on that …

method. Most of the tantalum, how ever, is smelted along with tin ore concentrate and then enriched in a slag.4 Depending on the ore types, the tantalum yield may vary between 40 and 85%. Slags with a high tantalum content of 8% Tap5 are digested in the same way as tantalum ore concentrates. Slags with a lower tantalum content

Three main types of Ta and Nb deposits exist (Linnen et al., 2013; Melcher et al., 2017) which could be grouped as: (i) carbonatites and associated rocks (pyrochlore: rich in Nb), (ii) alkaline to peralkaline granites and syenites (rich in Ta, Nb and rare earth elements), and (iii) granites and pegmatites of the lithium, caesium and tantalum (LCT) …

The tin system contributes to the tantalum supply. The niobium system cycle is tied up with the systems for crude steel and stainless steels. Niobium is indirectly recycled when crude steel and stainless steel is recycled. The niobium follows the existing alloy back into the cycle, and it is not subject to refining. This niobium does not get ...

According to Google, both of these photos show tantalum capacitors. For the heavier metal-cased ones I normally expect to see either a short straight tantalum lead coming out the + side with a copper lead attached to that, or a larger weld bead right next to the seal with a copper lead attached. Not in these types though, which always seems odd.

The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures. This causes the tantalum and niobium values to dissolve as complex fluorides, and ...

In 1903 von Bolton succeeded in producing tantalum powders by reduction of the double tantalum–potassium salt K2TaF7 with sodium. In the same year Siemens and Halske developed the first incandescent lamps in which a tantalum filament was substituted for the traditional carbon filament. In 1907 the same scientists used tantalum in rectifiers.
