Semi-Conductive Glaze

Semi-conducting glaze has industrial use for high voltage insulators. We used this composition of glaze: 70% SiO2, 9% Al2O3, 4.5% (K,Na)2 0.9% CaO, 7.5% ZnO and 33% SnO2+Sb2O5 in this study. The electrical properties of tin oxide-based glazes varied with amount of SnO2+Sb2O5. The conductivity of glazes consisting of SnO2 in Sb-doped are in the range 102–105 V/cm. The glazes were free of mobile ions such as K, Na, Li and Pb. Conduction takes place between Sb-doped SnO2 particles concentrated in the fused contact region between the much larger glass particles
