Bone filler prepared from natural calcium-containing waste and preparation method thereof
The invention relates to a bone filler prepared from natural calcium-containing waste and a preparation method of the bone filler. The preparation method comprises the following steps: (a) mixing 5-20% of calcium-containing waste powder, 5-20% of acetic acid and the balance of water to form a mixed solution; (b) adding 5-20 vol% of a diammonium hydrogen phosphate aqueous solution into the mixed solution to form a suspension; (c) adjusting the suspension into an alkaline solution; (d) carrying out precipitation reaction on the alkaline solution at room temperature for 0.1-72 hours, filtering the alkaline solution by centrifugation or air exhaust, taking out a precipitate, drying and grinding into hydroxyapatite; and (e) uniformly mixing 30-60% by weight of a pore-forming agent, 30-60% by weight of hydroxyapatite and the balance of an adhesive, putting the mixture into a mold, carrying out pressure forming, and carrying out a sintering procedure to obtain the bone filler, therefore, the method has the advantages of low cost and high yield.
本发明有关于一种天然含钙废弃物制备的骨填补物及其制备方法，所述制备方法包括下述步骤：(a)将5‑20％含钙废弃物末、5‑20％醋酸与剩余百分比的水混合以形成一混合液；(b)加入5‑20vol％磷酸氢二铵水溶液于混合液，形成一悬浮液；(c)将悬浮液调整为一碱性溶液；(d)将碱性溶液置于室温进行沉淀法反应0.1‑72小时，再利用离心或抽气过滤碱性溶液，取出一沉淀物烘干并研磨成羟基磷灰石；以及(e)将30‑60％成孔剂、30‑60％羟基磷灰石与剩余重量百分比的黏结剂混合均匀并放入一模具中加压成形，再进行一烧结程序以得到骨填补物；由此，本发明具有低成本及高产量的优点。
