ZnS ZnS CERAMICS FOR INFRARED TRANSMITTANCE AND METHOD OF MANUFACTURING THE SAME

摘要

Disclosed in the present invention are a ZnS sintered body for infrared transmission and a method for manufacturing the same. The method for manufacturing the ZnS sintered body for infrared transmission according to an embodiment of the present invention comprises a step of obtaining ZnS by mixing a zinc compound and a sodium compound with a solvent and conducting first thermal treatment; a step of conducting second thermal treatment of the ZnS which has undergone the first thermal treatment; and a step of forming a ZnS sintered body by sintering the ZnS which has undergone the second thermal treatment. According to one embodiment, impurities existing in ZnS can be removed.
