ABSTRACT:
A sintered body of tin oxide is made by forming a finely divided mixture containing at least about 0.2 weight percent ZnO, at least about 0.2 weight percent SiO.sub.2, up to about 0.5 weight percent Al.sub.2 O.sub.3, balance pure SnO.sub.2, with the sum of the proportions of ZnO and SiO.sub.2 being less than about 2 weight percent. The mixture is compacted and heated to a sintering temperature. The tin oxide may be doped with antimony.
