Various amounts of silver particles, 0.08-7.7 mol%, are mixed with zinc oxide powder and subsequently co-fired at 800-1200 โ€ข C. The effects of Ag addition on the microstructural evolution and electrical properties of ZnO are investigated. A small Ag doping amount (<0.76 mol%) promotes the grain grow
