制备无毒和生物相容的纤维或晶须是当今最紧迫的任务之一，因为大多数已使用的纤维材料（包括已使用多年的石棉）被认为是生物危害性的。以β-磷酸三钙（beta-Ca 3（PO 4）2：beta-TCP）为原料，柠檬酸水热法合成了具有良好生物相容性的羟基磷灰石晶须（Ca 10（PO 4）6（OH）2∶HAp）。晶须为单晶体，沿轴向沿着伸长，长20-30 μm，宽0.1 ~ 1 μm。它们稍微缺钙（Ca/P摩尔比= 1.63），并且在结构中含有微量的CO 32 −。
The preparation of non-toxic and biocompatible fibres or whiskers is one of the most urgent tasks today, because most of the fibrous materials which have been used (including asbestos which has been used for many years) are thought to be biohazardous. Whiskers of hydroxyapatite (Ca10(PO4)6(OH)2∶HAp), which is expected to be one of the best biocompatible materials, have been successfully synthesized by hydrothermal treatments of beta-tricalcium phosphate (beta-Ca3(PO4)2: beta-TCP) with citric acid. These whiskers were single crystals, elongated along thec-axis, with a length of 20–30 μm and a width of 0.1–1 μm. They were slightly calcium deficient (Ca/P molar ratio = 1.63) and they contained a trace of CO32−in their structure.
