Abstract

In this work, chemical solution derived Ca-doped zirconia fiber has been prepared by using calcium- and zirconium-naphthenate. Fibrous $ZrO_2$-CaO was drawn from a sticky mixture. Dried gel fibers were finally annealed at $1000^{\circ}C$ for 1 h in argon. 91 mol%$ZrO_2$-9 mol%CaO fiber consisted of tetragonal, monoclinic and $CaZrO_3$ phases after annealing at $1000^{\circ}C$. On the other hand, samples annealed at $500^{\circ}C$ consisted of almost tetragonal single phase. Homogeneous fibers surface at $500^{\circ}C$ became rougher after $1000^{\circ}C$-annealing. The sample annealed at $1000^{\circ}C$ with relatively rough surface structure showed a high Calcium phocphate forming ability.
