High Pressure Microscopy of the Silver and Cuprous Halides

摘要

Using a diamond pressure cell and a polarizing microscope, visual observations were made on the transformations of silver and cuprous halides at calculated pressures up to 125 kilobars. A new birefringent phase was observed in silver iodide at 2400 bars. Four phases were observed in CuI and CuBr while CuCl appeared to have only three.
