| 1 | 湿化学法合成羟基磷灰石晶体及其表征显示文摘采用湿化学法通过两种方案合成羟基磷灰石(hydroxyapatite,HA)晶体,一种方案是以Ca(NO3)2·4H:0和Na2HPO4作为原料,加入NaOH溶液调节pH值在10.5~11.0之间,不添加分散剂,在40℃水浴条件下合成羟基磷灰石;另一方案是在室温下(25℃)进行,在其他条件不变的情况下,以CaCl2·2H2O为钙源、乙醇胺作为分散剂合成羟基磷灰石.将两种方案合成的样品分别通过X射线衍射(X—raydiffraction,XRD)、傅里叶变换红外光谱(Fourier transform infraredspectroscopy,FTIR)、扫描电子显微镜(scanningelectronmicroscopy,SEM)、X射线能量色散仪(energy-dispersiveX-rayspectroscopy,EDX)、热重.差热分析和x射线光电子能谱(X—rayphotoelectronspectroscopy,XPS)进行表征.XRD和FTIR结果显示,合成的两种HA粉末都具有较高结晶度和纯度.SEM分析表明,第1种方案可合成直径为30—50nm,长50~150nm的棒状晶体;第2种方案则可制备粒径约100~150nm的球状(或椭球状)晶体.热分析表明,所制备的HA在1000℃范围内有显著的热稳定性.XPS和EDX分析则证实HA由Ca、P和O等元素组成,两种方案中钙和磷的摩尔比分别是1.60和1.63. | 巫剑波 秦草坪 袁秋华 郭志威 刘家裕 邓庆威 张培新 | 2015 | 深圳大学学报(理工版)2015，32，5： | 6 |

| 4 | Controlled Preparation and Formation Mechanism of Hydroxyapatite Nanoparticles under Different Hydrothermal Conditions显示文摘Hydroxyapatite(HAP) nanoparticles with uniform morphologies and controllable size were synthesized successfully by molecular template hydrothermal approach.The organic alcohols including ethanol,glycol,glycerol and butanol were used as templates to regulate the nucleation and crystal growth.The synthesized powders were characterized by X-ray diffraction,Fourier infrared spectrum and transmission electron microscopy.The results showed that the obtained HAP particles were uniform rod-like crystals,and the template molecular structures had significant effect on the morphology and size of HAP particles.The template molecules with longer hydrophobic groups resulted in longer particle length and larger aspect ratio.Compared with the concentration of template molecules,the template molecular structure showed larger influence on controlling the HAP morphology and size.Furthermore,the formation mechanism of these rod-like HAP particles prepared by alkyl alcohol templates was discussed.Moreover,hydrothermal treatment temperature and time could be also used for controlled preparation of HAP nanoparticles. | Shanyi Guang Fuyou Ke Yuhua Shen | 2015 | Journal of Materials Science & Technology2015，31，8： | 1 |
