Powdered tantalum case
Webducing tantalum powder is the reduction of potassium fluoro tantalate, K2TaF 7, by sodium. The tantalate is ob-tained by reacting pure fluoro tantalic acid solution by K 2CO 3. This is a typical case of liquid–liquid reduction. One can also prepare tantalum powder by reducing Ta 2O 5, but then the route is through hydriding/dehydriding of ... Web27 Mar 2024 · Tantalum capacitors can have a high density of capacitance. This leads to the following four use cases: Applications that require high stability. Applications that require no buzzing or other piezoelectric artifacts from the capacitors. Applications that require high reliability. Applications that require a high capacitance in a small form factor.
