Abstract

Electrostatic spray pyrolysis, a novel fabrication technique, has been used in this study to prepare calcium phosphate nano powders. Final annealing was done at $400^{\circ}C$ for 30min in air. The hydroxyapatite - forming ability of the annealed powder has been evaluated in Eagle's minimum essential medium solution (MEM). X-ray diffraction analysis, field emission - scanning electron microscope, energy dispersive X-ray spectroscope, and Fourier transform infrared spectroscope were used to characterized the annealed powders after immersion in MEM. The powder with an amorphous structure induced hydroxyapatite formation on their surfaces after immersion fer 15 days.

본 연구에서는 새로운 나노 분말 제조방법 중의 하나인 정전분무 열분해법을 이용하여 칼슘 포스페이트 나노분말을 제조하였다. 정전 분무된 분말은 공기 중에서 $400^{\circ}C$로 30분간 열처리하여 고상화하였다. 결정화된 분말의 하이드록시 아파타이트 형성능력을 평가하기 위하여 Eagle's minimum essential medium solution(MEM)을 사용하였으며, MEM 용액에 침전된 후의 분말의 특성평가를 위하여 X-선 회절 분석법, 전계 방사 주사형 전자 현미경, 에너지 분산 X-선 분광계 및 퓨리에 변환 적외선 분광계를 사용하여 분석을 행하였다. 비정질 구조를 가진 나노 분말은 MEM 용액에 15일 침전 후, 분말의 표면에 유도된 하이드록시 아파타이트 결정을 확인할 수 있었다.
