Abstract
PURPOSE:To manufacture a polycrystalline ZnSe body with high density, high purity and superior light transmission by a hot hydrostatic pressing method by pressing starting material at a lower temp. with a glass capsule, removing the capsule, and carrying out pressing at a higher temp. CONSTITUTION:A molding 2 of ZnSe powder is put in a glass capsule 1, and the capsule 1 is evacuated to a vacuum and sealed at a sealing part 3. The molding 2 is then compressed by hot hydrostatic pressing (HIP) at a relatively low temp. such as 900-1,200 deg.C at which the glass of the capsule is softened. At this time, the temp. is relatively low, so the ZnSe is not polluted by the glass components as impurities. The pressed ZnSe is taken out of the capsule 1 and subjected to HIP at a relatively high temp. of 1,300 deg.C to enhance the light transmission as well as to increase the density. Thus, a dense, high purity and transparent polycrystalline body almost free from voids and impurities is obtd.
