Abstract

Se produce un material de electrodo de tántalo, el cual tiene una tortuosidad extremadamente baja, un ISE excepcionalmente bajos, un funcionamiento de alta frecuencia extendido, una eficiencia volumétrica muy alta, y un consumo de tántalo reducido por ánodo. El material del ánodo se caracteriza por tener una sección transversal compuesta de placas de tántalo separadas que dan como resultado un electrodo altamente denso (eficiencia volumétrica). Las placas se interconectan eléctricamente, lo cual también se agrega a la estabilidad estructural del artículo. Esto se hace posible al poder controlar la geometría del material de tántalo durante el procesamiento. Un método para producir este material incluye extruir una moldura llenada con una mezcla (de preferencia geométricamente uniforme) de varillas de tántalo, y un material , y un metal extruible. Cuando la moldura se ha reducido lo suficiente en su tamaño, y se ha cortado, se remueve el material extruible disolviendo selectivamente con ácido. En adición a las ventajas anteriores, el artículo resultante es particularmente adecuado para utilizarse en las aplicaciones de superminiaturización.
