Abstract
鈣磷酸鹽類骨水泥的成分以鈣、磷為主,與人體的骨骼成分極度近似,
具有相當優良的生物相容性以及適當的機械強度,因為這些材料可在
室溫下自行硬化且具有高度之生物相容性和引導骨組織向內生長之
能力,使骨組織藉由表面遷移而延伸出高度生物相容性,因此可被作
為骨填充物來使用。本研究中,以磷酸鈣替代骨水泥之研究樣品,採
用硬化時間為控制因子,藉由光學顯微鏡(OM)、掃描電子顯微鏡
(SEM)、透射電子顯微鏡(TEM)以及能量色散譜(EDS)的拉曼
光譜儀等分析,為這個新式生物醫學材料磷酸鈣型骨水泥(CPC),硬
化時間和微觀結構,藉以研究探討此骨水泥材硬化時間對微結構改變
之關係,了解CPC 在不同硬化時間下,其材料之微結構相變化過程
情形、建立骨水泥顯微結構與硬化時間之關係。實驗結果顯示;樣品
經不同硬化時間製程後均呈現出多晶之晶體結構,較長硬化時間條件
下可表現出相對較高之緻密結構。
