Abstract
The invention relates to an electrical insulator coated with a semi-conducting tin oxide system glaze layer wherein the glaze layer contains 0.05 to 10 percent by weight of at least one metal oxide selected from the group consisting of niobium oxide, tantalum oxide, titanium oxide, zirconium oxide, yttrium oxide and tungsten oxide. The additional metal oxide reduces the dependance of resistance on the environmental temperature.
