Abstract

Mono dispersed cubic nano ZnS powders have been successfully prepared by using thioacetamide (CH3CSNH2) as source of S2-. The use of Na2S as sintering agent allows to lower the sintering temperature and to keep the cubic structure, leading to hot pressing sintered ZnS ceramics with approximately the theoretical density. The morphology and optical properties of the sintered ceramics have been studied.
