Hydroxyapatite whiskers and their preparation |
摘要 |
An apatite whisker has a mean aspect ratio (length along c-axis/length along a-axis) of not less than 10.0 and contains a carbonic acid group of not less than 0.01 wt. % based on total weight of the whisker. A method for preparing an apatite whisker involves precipitating and growing an apatite from a liquid containing phosphoric acid and calcium to have a mean aspect ratio (length along c-axis/length along a-axis) of not less than 10.0. |
