Abstract

The present invention relates to a method for preparing a ceramic powder from a bone of a bird's beak, a method for preparing biomedical or industrial ceramic materials by using the ceramic powder derived from a bone of a bird's beak, and a biomedical or industrial ceramic material prepared by the method thereof. The use of the present ceramic powder for manufacturing biomedical or industrial ceramic materials is safer than the use of the ceramic powder derived from allogenic bone or xenogeneic bone. In addition, the ceramic powder of the present invention can be prepared on a mass production basis. Furthermore, the ceramic material prepared using the ceramic powder of the present invention is more biocompatible than that prepared using artificially synthetic ceramic.

First claim

What is claimed is:

1. A method for preparing a ceramic powder from a bone of a bird's beak, which comprises the steps of:
(a) retrieving a bone from a bird's beak;
(b) removing a heterologous substance remaining in the retrieved bone of the bird's beak; and
(c) pulverizing the retrieved bone of the bird's beak into ceramic powder having a diameter of 400 um-500 um;

wherein the ceramic powder from a bone of a bird's beak has a ratio of calcium to phosphate of 1:1.45.

2. The method according to claim 1 , wherein the removal of the heterologous substance is carried out by (i) treatment with a chemical reagent selected from the group consisting of an aqueous solution of hydrogen peroxide, chloroform, methanol, sodium hypochlorite, and a mixture thereof, or (ii) heat treatment.

3. The method according to claim 2 , wherein the treatment with the chemical reagent is carried out by immersing the bone from a bird's beak in an aqueous solution containing 1-80 vol % of the chemical reagent under the temperature of 4-100° C. for 1-72 hours.

4. The method according to claim 2 , wherein the heat treatment is carried out under the temperature of 200-1500° C. for 1-24 hours.

5. The method according to claim 1 , wherein the bird is selected from the group consisting of a duck, a goose, a turkey, a chicken, a pheasant, a quail, and an ostrich.

6. A method for preparing a biomedical or industrial ceramic material which comprises the steps of:
(a) preparing a ceramic powder from a bone of a bird's beak by using the method according to claim 1 ; and
(b) forming a ceramic material by the heat treatment of (i) the ceramic powder derived from a bone of a bird's beak or (ii) mixture of the ceramic powder derived from a bone of a bird's beak and a heterologous ceramic powder under the temperature of 600-1500° C. for 1-3 hours,
wherein the ceramic material is a porous material having 5-98% porosity and the diameters of the pores of the ceramic material are in the range of 0.1 nm-5 mm.

7. The method according to claim 6 , wherein the heterologous ceramic powder is a naturally occurring ceramic powder or an artificially synthetic ceramic powder.

8. The method according to claim 7 , wherein the naturally occurring ceramic is derived from allogenic bone, xenogeneic bone or autogenous bone.

9. The method according to claim 6 , wherein the artificially synthetic ceramic is selected from the group consisting of hydroxyapatite (HA), dicalcium phosphate (DCP), tricalcium phosphate (TCP), tetracalcium phosphate (TTCP), zirconia, alumina, glass, and mixture thereof.

10. The method according to claim 6 , wherein step (b) further comprises adding a polymer into (i) the ceramic powder derived from a bone of a bird's beak, or (ii) the mixture of the ceramic powder derived from a bone of a bird's beak and the heterologous ceramic powder.

11. The method according to claim 10 , wherein the polymer is selected from the group consisting of polyester, polyimide, polyether, aramide, polystyrene, polypropylene, polymethyl methacrylate, polyalkylene naphthalate, polyvinyl alcohol, acrylic resin, gum resin, phenolic resin, epoxy resin, teflon polymer, and copolymer thereof; polydioxanone, polyglycolic acid, polylactic acid, polycaprolactone, lactic acid-glycolic acid copolymer, glycolic aicd-trimethylcarbonate, glycolic acid-ε-caprolactone, polyglyconate, polyglactin, polyamino acid, polyanhydride, polyorthoester, mixture thereof, and copolymer thereof; collagen, gelatin, chitin/chitosan, alginate, albumin, hyaluronic acid, heparin, fibrinogen, cellulose, dextran, pectin, polylysine, and polyethyleneimine.

12. The method according to claim 6 , wherein the formation of the ceramic material in step (b) is carried out by a method selected from the group consisting of emulsification method, phase-separation method, solvent diffusion method, compression method, particle leaching method, liquid nitrogen method, bubble formation method, polymer spongy template method, solvent spinning method, melt spinning method, wet spinning method, air spinning method, melting molding method, solvent molding method, particle addition method, and prototyping method using computer aided design (CAD).

13. A biomedical or industrial ceramic material, which comprises (i) a ceramic powder derived from a bone of a bird's beak; (ii) a mixture of a ceramic powder derived from a bone of a bird's beak and a heterologous ceramic powder; or (iii) a mixture of a polymer and said ceramic powder of (i) or (ii), wherein the ceramic material is a porous material having 5-98% porosity and the diameters of the pores of the ceramic materials are in the range of 0.1 nm-5 mm; the ceramic powder from a bone of a bird's beak has a ratio of calcium to phosphate of 1:1.45; and the ceramic material is prepared by the method according to claim 6 .

14. The biomedical or industrial ceramic material according to claim 13 , wherein the ceramic material is in a form selected from the group consisting of a block, film, filament, fiber, membrane, mesh, woven fabric, nonwoven fabric, knit, granule, particle, plate, bolt, nut, nail, and a combination thereof.
