摘　　要：目的运用撞击流沉淀法制备法制备纳米羟基磷灰石(HAP)。方法并用X射线衍射、红外光谱、透射电镜对纳米羟基磷灰石进行了表征和形貌分析。结果采用浸没循环撞击流反应器可得到直径15nm、长度50nm～70nm左右的纳米羟基磷灰石棒状颗粒。结论此方法制备的羟基磷灰石,尺寸分布均匀,是制备HAP的好方法。Objedtives To obtain Hydroxyapatite (HAP) nano-rods/whiskers with well-controlled sizes. Me-thods Hydroxyapatite (HAP) nano-rods/whiskers are prepared by precipitation in the submerged circulativeimpinging stream reactor (SCISR). Results While pH = 12.5, the dripping time of the di-ammonia phosphatesolution is 54mL · min-1 and the stirring rate is 1200r.min-1, the uniform sized hydroxyapatite nano-whiskerswith the size of 15nm in diameter and 50nm^70nm in length can be obtained in SCISR. Conclusions The sub-merged circulative impinging stream reactor (SCISR) is especially suitable for the preparation of ultrafine particlesby reaction-precipitation and exhibits very well performance.
