The Influence of Thermal Processing with H2 Atmosphere on the Physical Properties and Microstructure for use in Electrolytic Capacitors of Nb

This study evaluated the effect of thermal processing in hydrogen (H2) and argon (Ar) atmospheres on the physical and microstructural properties of niobium (Nb) powders for electrolytic capacitors. Nb powders were treated at 750 °C, 850 °C and 950 °C with isothermal holds of 60 min and 120 min—sampl...
