SOLID TANTALUM CAPACITOR
Abstract
Carbon analysis equipment was placed in service and carbon analysis made for several types of experiments including change of apparent carbon content during formation in various electrolytes. Mass spectrometer type qualitative analyses are shown for gases evolved during anodization in different electrolytes. Doping experiments on high purity tantalum were begun. Work with carbon and iron is reported with metallographic and microhardness results shown. A brief description is given of experiments with anodes made in a range of densities. Compacting studies and die lubricant evaluations were completed. The extreme importance of surface cleanliness and ways of showing the effects of unclean surface conditions are reported. A voltage capability test method is reported for determining ability of anodes for use in 100 vdc solid capacitors. Calculations based on physical characteristics of anodes along with electrolyte character show the need for certain anode structures. Processing methods for 100 vdc solid capacitors were chosen for use in pilot production of the samples. (Author)
