快速均匀沉淀法制备纳米级HAP粉末

Nanosize HAP Powders Prepared by Quick Homogeneous Precipitation Method

尝试采用快速均匀沉淀法制备了纳米级HAP粉末。 70℃干燥的粉末 ,进行XRD分析 ,主晶相为HAP ,但结晶性不好 ;经 75 0℃焙烧后 ,得到了结晶性比较好的HAP粉末 ,晶粒大小约为 80nm。该法与湿法相比 。

In this paper,the nanosize HAP powder was prepared by the quick homogeneous precipitation method.It was observed by XRD that the main crystal phase of powder dried at 70℃ was HAP, but the crystallinity was bad;The crystallinity of HAP calcined at 750℃ was better,and the grain size of powder was about 80nm.The preparation cycle of this method was greatly shorten,compared to wet method.
