The strontium substituted hydroxyapatite (SrHA) whiskers with 6.6mol% of Ca replaced by Sr were successfully synthesized via homogeneous precipitation method. The product had a width of 0.2–8μm and length up to 155μm. The human osteoblast-like cell (MG-63) culture showed that Sr substitution could stimulate the proliferation of MG-63 at certain extracted concentrations. Furthermore, the addition of SrHA whiskers could significantly improve the mechanical properties of calcium phosphate cement (CPC). The 5wt.% SrHA whisker reinforced CPC revealed the highest compressive strength of 2.92MPa, which was almost 2-times higher than that of the pure CPC. Our study indicated that SrHA whisker might be a potential candidate as a new bioactive and mechanical reinforcement material for hard tissue regeneration applications.
