摘要

报道了用作碘穆斯堡尔源的新材料碲酸镁（Mg

TeO

）研制。碲酸镁具有高熔点（1420℃）和高的德拜温度（320K），碲以Te

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。

Abstract

The preparation of Mg

TeO

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

TeO

have the advantage of simplicity and do not need any after-treatment. The quality of Mg

TeO

has been determined by X-diffraction

differential thermal and neutron activation analysis. The results show that Mg

TeO

is an ideal material as a Mössbauer iodine source.
