Abstract
The present invention provides a fibrous product of apatite comprising one or more apatites selected from a group of apatites represented by the general formula: EQU M.sub.10 (ZO.sub.4).sub.6 X.sub.2 wherein M represents Ca, Ba, Mg, Sr, Pb, Cd, Fe and the like, ZO.sub.4 represents PO.sub.4, AsO.sub.4, VO.sub.4, CO.sub.3 and the like, and X represents F, Cl, OH and the like. This fibrous product of apatite has many applications such as uses for medical treatment, large scale microorganism cultivating media and others, and particularly it is useful as apatite implant materials having a good compatibility with living organism and superior workability. A fibrous apatite product of this invention may be produced by a method comprising the steps of: PA1 (a) preparing a dispersion of apatite by dispersing fine apatite particles uniformly in a solution of binder in water, said apatite being one or more apatites selected from a group of apatites represented by the general formula: EQU M.sub.10 (ZO.sub.4).sub.6 X.sub.2 PA1 wherein M represents Ca, Ba, Mg, Sr, Pb, Cd, Fe and the like, ZO.sub.4 represents PO.sub.4, AsO.sub.4, VO.sub.4, CO.sub.3 and the like, and X represents F, Cl, OH and the …
