A brief discussion on the preparation technology of high-purity ytterbium metal

YtTerbium metal has excellent photoelectric properties, such as low work function, high transmittance, relatively high stability and low surface plasma effect. Most rare earth metals react with hydrogen to form trihydrides and break and pulverize, while ytterbium only forms dihydrides under low pressure, which are smaller in size and do not break, which is conducive to the application of hydrogen and its isotopes; within 0 ~ 4 GPa, ytterbium metal will not change phase, and has a high piezoresistance coefficient. It is the best material for pressure sensors and has very important applications in blasting measurement and protection engineering.

The excellent functionality and spectral characteristics of metal ytterbium make it widely used in pressure sensing materials, shielding coating materials, laser materials, cathode materials and fiber optic communication amplification materials. In recent years, the application of metal ytterbium in the field of high-end display materials has shown explosive growth. Ytterbium in high-performance Yb/Ag cathode materials for OLED displays can reduce the device's electron injection barrier and improve the balance of carriers in the device, making the display screen highlight the characteristics of low energy consumption, high resolution and high color saturation.

Therefore, the stable preparation technology of high-purity ytterbium metal has broad development prospects. The purity of ytterbium metal is one of the important factors affecting the performance of materials. The ytterbium target used in OLED requires a product purity of 4N5 or above, and the price is more than double that of ordinary ytterbium metal. Vacuum distillation is currently one of the most commonly used and most effective methods for purifying ytterbium metal, with the advantages of simple equipment, short process flow, and strong controllability.
