Abstract
A method of producing a hydroxylapatite base porous beads filler for an organism, including mixing hydroxylapatite powder having particle sizes not larger than 125 .mu.m, in an amount ranging from 40 to 90% by weight, synthetic resin powder having particle sizes not larger than 74 .mu.m, in an amount ranging from 5 to 55% by weight, and resinous binder in an amount ranging from 0.5 to 5% by weight to obtain a mixture, granulating the mixture to form beads each having a diameter ranging from 0.03 to 25 mm, firing the beads at a temperature ranging from 900.degree. C. to 1180.degree. C. to form hydroxylapatite base porous beads, dipping the porous beads in a colloidal solution, removing air from the porous beads under vacuum, and filling the colloidal solution into the pores in the porous beads under pressure.
