以Ca（OH）2和CaHPO4·2H2 O为原料，采用水热法合成了羟基磷灰石（HA）晶须和晶体。已经研究了相对于pH = 6 - 14、温度= 60 - 140 ℃的不同条件，以确定它们对HA颗粒结构和形态的影响。结果表明，pH值是改变形貌的重要参数变量。在pH = 9和温度= 120 ℃的条件下，获得了良好伸长的颗粒。这些HA晶须是长径比> 20的单晶，典型的直径和长度分别为40和600纳米。(C)2003年Elsevier Ltd和Techna S.r.l. All rights reserved.
Hydroxyapatite (HA) whiskers and crystals were synthesized by hydrothermal treatment of Ca(OH)(2) and CaHPO4.2H(2)O. Different conditions relative to pH = 6-14, temperature = 60-140 degreesC have been investigated in order to ascertain their influence on the HA particle structure and morphology. Results have shown that pH value is a significant parameter variable in altering the morphology. Well elongated particles were obtained on condition that pH = 9 and temperature = 120 degreesC. These HA whiskers were single crystals with an aspect ratio > 20, a typical diameter and length of 40 and 600 nm, respectively. (C) 2003 Elsevier Ltd and Techna S.r.l. All rights reserved.
