Crystallization Mechanism of Oxide Film on Tantalum Anode Surface
With the development of high specific capacitance and miniaturization of tantalum capacitors,flake tantalum powder of 15 000～20 000 μFV/g specific capacitance has been put into production and used by capacitor manufacturers.Based on the analysis of the results of SEM,particle strength,particle size distribution,porosity and sintering curve of two different powders,new requirements and suggestions for the preparation of 15 000～20 000μFV/g specific volume chip tantalum powder were put forward.
