Abstract

칼슘염을 유기 용매에 용해시켜 칼슘 용액을 제조하는 단계; 알콕사이드를 유기 용해시키고, 생성된 용액을 물을 첨가하여 알콕사이드 용액을 제조하는 단계; 상기 알콕사이드 용액과 칼슘 용액을 혼합하는 단계; 생성된 혼합 용액을 교반하는 단계; 상기 혼합용액에 촉매를 첨가하여 졸을 형성시키는 단계; 및 생성된 졸을 교반하고 건조하여 겔을 형성시킴으로써 조성이 균일한 고순도의 수산화아파타이트를 효율적으로 생산할 수 있다.Dissolving the calcium salt in an organic solvent to prepare a calcium solution; Organic dissolving the alkoxide and adding the water to the resulting solution to prepare an alkoxide solution; Mixing the alkoxide solution and calcium solution; Stirring the resulting mixed solution; Adding a catalyst to the mixed solution to form a sol; And by stirring and drying the resulting sol to form a gel it is possible to efficiently produce a high purity apatite with a uniform composition.
