Application of tomography in microreactors

Progress in the Application of Rare Light Metal Beryllium

“…In high-resolution medical radiography equipment, at present, beryllium is the sole X-ray window material, and no material can adequately replace beryllium, such as computed tomography (CT), ultrasound diagnostic monitors. In industrial analytical equipment, beryllium is used as the window material for those used in electron microscopy, industrial X-ray flaw detectors, X-ray fluorescence analysis, proportional and scintillation counters [34].…”

The 5-micron beryllium foil obtained by vacuum coating method was recently used to produce an advanced speaker diaphragm, which not only exhibited a high sound propagation speed, but also extended the upper limit of high frequency from the original 23 kHz to 40 kHz.…”
