Abstract: Bioactive ceramic fiber has widely demands in tissue engineering.In virtue of physical and chemical properties of silk,the preparation of hydroxyapatite slurry by using sol-gel method and to adsorb the slurry on surface of silk treated by a series of disposals and simultaneously to be consolidated on the surface were studied.Subsequently the bioactive calcium phosphate ceramic fibres with preferable tropism were prepared through reasonable design of sintering process of ceramic.
