| 摘 要： | 硅酸钙用作生物材料的研究近年来引起了人们的关注,因其良好的生物活性而有望在生物医学领域得以应用.本文利用含Ca2+和SiO32-的溶液、以EDTA(乙二胺四乙酸)为螯合剂,通过在普通高压釜中200℃,5h水热反应,首次制备了直径、长度分别为0.1-1μm、40-100μm这样大尺寸的生物活性托贝莫莱石晶须,并且对托贝莫莱石晶须的形成机理进行了初步的探讨.

| Abstract: | Due to its good bioactivity, calcium silicate is potentially a candidate in the biomedicine field. A novel method for synthesizing tobermorite fibers was developed. Tobermorite fibers can be synthesized successfully by the hydrothermal reaction at 200℃ for 5h using a Ca(II)-EDTA complex precursor. Tobermorite fibers obtained in the present work were 40-100μm in length and 0.1-1μm in diameter. The properties of tobermorite fibers were characterized by XRD, SEM techniques. And the formation mechanism was proposed. |
