摘　　要：HAP是良好的骨替代材料,钡的加入能够提高HAP的降解性能和生物活性。以硝酸钙、硝酸钡、磷酸氢二铵为原料,在94℃恒温条件下制备出了掺钡羟基磷灰石晶须。通过XRD、FT-IR、SEM和EDS对其进行表征,结果表明:钡可以掺入羟基磷灰石晶须中,所得晶须长径比高、均一性好。Hydroxyapatite is well used as bone repair materials. Degradation property and biological activity can be further improved with barium addition in the HAP crystals. Barium-doped Hydroxyapatite whiskers with different content of Ba were produced with calcium nitrate, barium nitrate and diammonium phosphate at 94℃. The whiskers were character- ized by XRD,FT-IR,SEM and EDS. It was indicated that barium can be doped in hydroxyapatite with proper process and barium-doped hydroxyapatite whiskers were produced successfully.
