The apatite deposition on the raw silk fiber cloth was accelerated when the fibers were subjected to treatment with CaCl(2) solution at a concentration of at least 1 kmol/m(3) before immersion in 1.5SBF. Apatite deposition also was observed on the sericin film after the film was soaked in 1.5SBF for 7 days.
The surface morphology of the films can be controlled by sol–gel processing parameters such as different precursors [9], post heat-treatment [10] and addition of chemical additives [11]. The film solubility can be lowered by enhancing the apatite phase to develop well [12] and incorporating fluorine into the apatite phase [13].
