Аннотация:The Ssp values of zinc substituted HAs are consid erably lower than those of silversubstituted HAs. A decrease in Ssp with an increase in the substituting ion (zinc or silver)content is associated with an increase in the degree of aggregation of particles. As in known,smaller particles have a larger surface curvature radius and, hence, a higher activity anddegree of aggregation [7]. An increase in the zinc or silver ion content in the apatite structureleads to an increase in particle size. According to SEM and TEM, the zinc substituted HA …
