We introduce high-pressure study on amorphous materials using a multi-anvils press equipped with the X-ray transparent cBN anvils. First, we mention merits of the angle-dispersive X-ray diffraction system compared with the conventional energy-dispersive system. Next, we show the results of the verification of the high-pressure formation of the elemental bulk metallic glass as an example. Finally, the characteristics of X-ray absorption are shown both for the combinational sintered diamond anvils and the presently used cBN anvils.
