| 摘 要： | 为了对比纳米HA与大颗粒或大晶粒HA作为骨填充材料在动物体内的实验效果，通过改变烧结工艺来获得大颗粒或大晶粒HA．扫描电镜检测结果表明，烧结温度对粒子尺寸的影响最为敏感：低于800℃烧结时，粒子长大缓慢甚至没有长大现象；超过900℃后，粒子迅速长大；1200℃烧结时，随烧结时间延长，晶粒呈现不规则长大，并出现二次再结晶现象。

| Abstract: | In order to compare the difference between nano-HAp and bigger size of HAp as the bone-implanting materials in the animals, the sintering process was adjusted and the bigger size of HAp was gotten. The influence of sintering temperature and time on the size was investigated:the size of particle is the most sensitive to the sintering temperature, in low sintering temperature extent where the particles grow slowly or even stop, while the particle could be more quickly and would show recrystallization when it exceeds some certain temperature. It also appears the phenomenon of the recrystallization with the increase of sintering time. |
