1. Aging and Characterization of Semiconducting Glazes
Abstract : Semiconducting glazes on ceramic insulators had been introduced as a solution for improving the performance of high voltage insulators especially under heavily polluted conditions. The major concern in using such glazes, despite their approved advantages, is the observed aging of the surface with exposure time, leading to reduction of conductivity and deterioration of the glaze itself, especially under dc voltage.

3. Characterization of Ceramic Raw Minerals in Uganda for Production of Electrical Porcelain Insulators
Abstract : In this work an extended literature survey on ceramics and porcelains in particular, has been documented. Samples from two Ugandan deposits of each feldspar and quartz were characterised by means of X-ray diffraction, thermal analysis, chemical analysis and scanning electron microscopy and found to possess requisite properties for making electro porcelain insulators.
