PbSe and PbS are both volatile and difficult to densify by normal sintering. We tried to sinter these compounds in a closed system, that is, by hot isostatic pressing in a glass capsule. Hot isostatic pressing was carried out for these compounds on the basis of their thermal behaviors in air as studied by TG‐DTA. The maximum bulk densities obtained were 8.10 and 7.50 g/cm 3 , respectively, corresponding to their theoretical densities. The microstructures of the isostatically hot‐pressed bodies were also observed by SEM. The present work shows that ceramic compounds which are normally volatile can be densified by encapsulation in glass followed by hot isostatic pressing.
