Abstract

The effect of substituting 0–30 mass-% quartz by technical alumina in an electrical porcelain insulator was studied. The structural and thermomechanical characteristics of siliceous porcelain were examined after industrial firing at 1260°C. A remarkable improvement was observed in the thermomechanical and microstructural qualities of well-formed electrical porcelain bodies, with the best results occurring for the composition based on 20 mass-% substitution of alumina.
