Apatite ceramics Ca 10 (PO 4 ) 6 X 2 ( X = F , OH ) were prepared by the standard solid state sintering method and irradiated with He ions under a fluence of 5 × 10 16 ions/cm 2 at 450 °C. Irradiation induced formation and growth of the He bubbles were observed by a transmission electron microscope. Hydroxyapatite Ca 10 (PO 4 ) 6 (OH) 2 and fluoroapatite Ca 10 (PO 4 ) 6 F 2 with different He bubble morphologies indicate the influence of OH – / F – substitution on the He-ion annealing efficiency, as well as the structure itself, which affects the process of He bubble evolution and formation. The grain boundaries also act as sinks to accumulate He bubbles. No obvious irradiation damage but slight intensity reduction and left shift of diffraction peaks were observed according to the grazin...

氦气在高温下磷灰石结构中气泡的形成

通过标准的固态烧结法制备磷灰石陶瓷Ca 10(PO 4)6 X 2(X = F,OH),并在450℃下以5×10 16离子/ cm 2的通量辐照He离子。通过透射电子显微镜观察到辐射引起的He气泡的形成和生长。具有不同He气泡形态的羟基磷灰石Ca 10(PO 4)6(OH)2和氟磷灰石Ca 10(PO 4)6 F 2指示OH-/ F-取代对He离子退火效率的影响。结构本身,影响着氦气泡的演化和形成过程。晶界也可以作为汇聚氦气气泡的汇。根据grazin,没有明显的辐射损伤,但观察到轻微的强度降低和衍射峰的左移。
