    • Cryogenic grinding of tantalum for use in capacitor

      Dec 06, 2016 · Electrolytic capacitors typically comprise anodes comprised of tantalum. At room temperature, tantalum is a ductile material that makes milling of the material difficult. Thus, in order for tantalum to be milled to a desired particle size, it is usually embrittled through the use of a hydrogen embrittlement process.
