Four porcelain composites comprising kaolin (27-37%), beach sand (20-24%), ball clay (13-18%) and feldspar (25-40%), wereformulated and characterized using powder XRD, SEM and particle size distribution analysis in order to determine theirpotential for use as electroporcelain insulators. Chemical, mechanical and electrical properties were also evaluated. Each ofthe formed samples were compressed at 200 MPa and sintered at 1250 oC for 1 hour. Bending strength results of the porcelainbodies showed increase in bending strength with reduction in particle sizes. An increase in dielectric strength was found forsamples with a higher felspar content. The XRD pattern for all the sintered samples showed the presence of quartz and mullitephases in the body at different intensities. Samples with lower particle sizes showed similar electrical and mechanicalproperties to commercially available electroporcelains albeit at a cheaper cost of production.
