Hydrothermal Synthesis of Tobermorite Fibers through Calcium Chelated Complex

Abstract

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.

Key words: tobermorite fibers, calcium chelated complex, hydrothermal synthesis, bioactive
