Electric porcelains are widely used for insulation purposes. The aim of this study is to characterize feldspar and quartz raw materials in Uganda for use in manufacture of electric porcelains. Samples from two deposits of each feldspar and silica are investigated to assess their potential as raw materials in the manufacture of electric porcelains. Raw samples ground to powder form are investigated by means of X-ray diffraction, thermal analysis, and scanning electron microscopy. In addition, the chemical composition, particle size distribution and density of the powders are determined. The study reveals one of the feldspar deposits to consist of purely ordered microcline, while the other has ordered microcline, quartz and albite. The silica deposits are purely of quartz mineral. The materials investigated, are suitable for use in porcelain production.
