Zinc sulfide and zinc selenide ceramic samples prepared by hot pressing (HP) and chemical vapor deposition (CVD) have been subjected to dry grinding simulating dust erosion of these materials under real service conditions. It has been demonstrated that photoluminescence measurements allow one to follow the degradation of the crystal structure of ceramic grains by monitoring the intensity of structure-sensitive emission bands. The crystal structure of ZnS, a harder material, has been shown to be less sensitive to abrasion. Moreover, the abrasion resistance of the ceramics produced by CVD exceeds that of the HP ceramics of the same composition.
