Point defects and possible reasons for defect formation in beryllium ceramics with B3+, Al3+, Zn2+, Li+, and rare-earth element impurities produced by slip casting, dry-press molding, and high-temperature compression are investigated using electron paramagnetic resonance. A certain number of impurity centers are identified which determine the optical, luminescent, diffusion, and other physicochemical properties of beryllium ceramics.
