The aim of this work was the determination of the effects of gelling the electrolytes used in electrolytic capacitors of the type Ta/Ta2O5/gel electrolyte/counter electrode. The investigation was divided between two main areas: firstly, the ionic conductivity of gel electrolytes was examined using Pt/Pt black electrodes; secondly, the influence of various electrolytes on the properties of tantalum and Ta/Ta2O5 electrodes, and on the electrolytic capacitors was examined. The conductivity of a series of gels prepared from fumed silica and 40% sulphuric acid showed a non-linear dependence on silica content, but was sensitive to the method of preparation. A standard mixing technique was developed and the reproducible conductivity of gels prepared by this method showed a linear decrease with increasing silica content.
