Densification of high-purity zinc sulfide was studied by the normal sintering at 800°-1200°C for 2h and hot-pressing at 700°-1100°C under the pressure of 10-40 MPa for 1 to 4h. Zinc sulfide densified slightly in normal sintering and marked grain growth accompanied by a slight increase in density was found above 1000°C. High density was achieved by the hot-pressing between 800° and 1000°C and under the pressure of 40MPa. The grain size was approximately 1μm, and no significant grain growth was observed below 900°C. Above 1000°C, the grain growth became increasingly significant with increasing temperature. At 1100°C, high density was not attained; phase transformation and abnormal grain growth were responsible.
