BONE VOID FILLER AND METHOD FOR MANUFACTURING THE SAME BY NATURAL CALCIUM-CONTAINNG WASTE
The present invention discloses a bone void filler and a method for manufacturing the same by natural calcium-containing waste, which comprises steps of mixing 5-20 wt% of a calcium-containing waste powder, 5-20 wt% of acetic acid and a remaining weight percentage of water uniformly to obtain a mixing solution; adding 5-20 vol% of a diammonium hydrogen phosphate solution to the mixing solution to obtain a suspension; controlling a pH value of the suspension to obtain an alkaline solution; leaving the alkaline solution at room temperature for precipitation for 0.1 to 72 hours, centrifuging or suction filtrating the alkaline solution to obtain a precipitate, drying and grinding the precipitate to obtain hydroxyapatite; and mixing 30-60 wt% of a pore former and 30-60 wt% of the hydroxyapatite and a remaining weight percentage of a binder uniformly to form a mixture, compression molding the mixture in a mold and sintering the compression-molded mixture.
