Samples made of biogenic hydroxyapatite–glass composites containing cerium and lanthanum oxides are produced and examined. The emphasis is placed on composites containing 50.3% hydroxyapatite and 3, 5, or 7% CeO2. It is established that these amounts of cerium dioxide change the color of the samples, somewhat increase their total porosity and compressive strength, and scarcely change their microstructure and solubility in physiological solution. Additions of cerium dioxide have no effect on the biochemical solubility of alloyed samples and thus the use of such materials in surgery to replace bone sections subjected to substantial mechanical loads is beneficial.
