• Xrd and tem patterns showed that superfine powders of namometer oxide , 15 ~ 98nm ca . , even and without hard agglomeration , can be synthesized by this method , what ' s more , the size of the powders will be increased as the increasing of the concentration of starting solution , temperature and time for calcining . so products with needed size can be synthesized by choosing the appropriate conditions
  产物超细粉的xrd和tem图谱表明，该方法可以合成粒径为15 98nm左右、分布较为均匀、没有明显硬团聚的纳米氧化物超细粉，而且其粒径会随起始溶液浓度的增加、凝胶煅烧温度的升高和煅烧时间的增加而增大。
• The formation process and mechanism are investigated : the adding of n ( ch2ch2oh ) 3 promoted the dissociation of cf3cooh in the starting solution and some non - volatile , fluorine containing intermediates can be remained after tray - drying of the solution . during the following heat - treatment process , the intermediates decomposed and further react with the rest amorphous calcium phosphate , leading to the final formation of fha or fa phase . the fluorine content in the fha phase obtained could be tailored by the content of cf3cooh added .
  发现cf _ 3cooh只有在加入n ( ch _ 2ch _ 2oh ) _ 3的条件下才能形成fha相和fa相，其机理是：在溶液中加入n ( ch _ 2ch _ 2oh ) _ 3能够促进溶液中cf _ 3cooh的离解，形成无挥发性的含氟过渡化合物，溶液快速干燥后的中间产物中仍能保留过渡性的含氟化合物，在随后的热处理过程中，过渡化合物分解并与非晶态的钙磷酸盐反应最终生成fha相或fa相。
