Abstract: | Starting with powdered Hg1−xCdxTe, several tie-lines at 500 and 560°C were established using an energy dispersive spectrometer on a scanning electron microscope
for the quantitative analysis. After holding at 500 or 560°C for time periods based upon the powder size and the published
interdiffusion constant, then water quenching to room temperature, the primary grains were found to be uniform in composition
and covered with a 5-6 μ layer of HgTe or low x Hg1−xCdxTe. The primary grain and overall compositions establish directions for tie-lines that are in good agreement with published
experimental and theoreti-cal results. |
