| 摘 要： | 目前在国际上已开发出制备羟基磷灰石(Ca10(PO4)6(OH)2:HAp)纤维的新颖方法。羟基磷灰石纤维可通过在空气中1000℃的温度加热一种压缩块来成功地加以合成,这种压缩块由β-磷酸钙(β-Ca(PO3)2)纤维和(Ca(OH)2)颗粒组成,压缩之后用稀盐酸水溶液加以处理。压缩块中的β-Ca(PO3)2纤维和Ca(OH)2经过加热就转变成了纤维性的HAp和CaO相,其中的CaO经过酸洗而除去。在这种情况下获得的HAp纤维长度为40～150μm、直径为2～10μm。它们与β～Ca(PO3)2纤维的尺寸大小几乎差不多。

| Abstract: | A novel method for preparing calcium hydroxyapatite (Ca10(PO4)6(OH)2:HAp)fibers has been developed. Hap fibers can be prepared successfully by heating a compact consisting of calcium metaphosphate (β-Ca(PO3)2)fibers with Ca(OH)2 particles in air at 1000℃ and subsequently treating the β-Ca(PO3)2 fibers and the Ca(OH)2 in the compact were converted into fibrous Hap and CaO phases by the heating, and the CaO phase was removed by acidleaching. Hap fibers obtained in the present work were 40～150μm in length and 2～10μm in diameter. The fibers had almost the same dimensions as those of the β-Ca(PO3)2 fibers. |
