借助正交设计法设计试验方案,以磷石膏为原料制备纳米羟基磷灰石,利用FT-IR、XRD、SEM等手段对样品进行结构表征与分析。试验结果表明:所制备出的纳米羟基磷灰石呈球形,其平均直径为97nm,且分散性好,大小均匀。
With the help of orthogonal test design,nanometer hydroxyapatite was prepared from phosphogypsum,the sample was characterized by FT-IR、XRD、SEM.The result showed that nano-hydroxyapatite was globular;the mean diameter of nano-hydroxyapatite was 97nm,which was very fine and well dispersive.
