In this research the effect of increment in concentration (X) which is used in the preparation of Hg1-x cdx Te alloys in the laboratory on its structural properties (x-ray testing , atomic absorption testing) was studies within the range of and all other effecting where taken in to consideration.
The first part of the structural properties testing included testing the alloys by using x-ray diffraction. The results shouldexplainthe composition of all alloys is of polycrystalline type mean. While the second testing was through the calculation of (X) concentration in the MCT alloys after it was prepared using an atomic absorption spectroscopy analysis and the tested results show the matching between its concentrations with the ones that were already used in its preparation.
