存在于化合物中,形成高配位完整立方结构,能代替ZnTe、SnTe作碘的穆斯堡尔源。对所研制的碲酸镁进行了X-衍射、差热及中子活化分析测试,证明从结构到纯度都达到作为碘穆斯堡尔源的要求。
The preparation of Mg
as an iodine Mössbauer source is described
It has a high melting point(1420℃) and a high Debye temperature(320K). Te in the compouud is in the from of Te
ion
with a structure having high coordination number and perfect cubic symmetry. As a substitute for ZnTe and SnTe sources
this source might be used for the Mössbauer measurements at room temperature. The preparation methods of Mg
have the advantage of simplicity and do not need any after-treatment. The quality of Mg
has been determined by X-diffraction
differential thermal and neutron activation analysis. The results show that Mg
is an ideal material as a Mössbauer iodine source.
