摘要：
The properties of zirconium ceramics can be improved by combination with calcium phosphate compounds, which impart bioactivity to the bioinert material. The effect of Ta2O5 on some properties of ceramics was studied. Tantalum oxide doping increases the radiopacity of calcium phosphate zirconium ceramics, but deteriorates the mechanical and bioactive properties. This ceramics can be proposed as a material for replacing bone tissue defects. The material was shown to have sufficient strength, radiopacity, and developed microrelief and to contain a bioactive phase. The obtained materials meet conditions necessary for the replacement therapy. The method can be used to produce a material with specified characteristics for the manufacture of individual implants.
