1.Increasing the K2TaF7 concentration in an oxyfluoride-chloride electrolyte results in tantalum being deposited in the form of powder consisting of spheroidal particles and increases the powder particle size.2.The coarsest electrolytic tantalum powder, composed of multiple spheroids, is obtained at a KC1/KF weight ratio in the bath equal to 1/1, while the finest powder is obtained from dendritic deposits forming during the electrolysis of K2TaF7-KCl-Ta2O5 and K2TaF7-KF-Ta2O5 melts.3.The particle size of electrolytic tantalum powder can be decreased by raising the melt temperature or increasing the cathodic current density. |
