Application of Lanthanum Hexaboride:

Because the B6 octahedral network needs two electrons to stabilize its structure, the three valence electrons of La will have one rich, and LaB6 behaves as a metal conductor. The surface plasmon resonance absorption of the metallic conductor LaB6 nanomaterial is about 1000nm, which can make up for the shortcomings of ITO (Indium Tin Oxide) and other infrared blocking materials that have poor blocking effect in the near infrared region, making LaB6 an important infrared blocking material. Due to the strong covalent bond between B atoms in the LaB6 structure, a tight spatial network is formed, which makes it have the characteristics of low volatility, low work function, high melting point, high strength and high stability, making it an important field emission Materials, widely used in cutting-edge instruments such as electron microscope filaments. Its density is 4.7g/cm^3. There are many compounds between B-La elements, such as LaB2, LaB4, etc., among which LaB6 is relatively stable. Traditionally, LaB6 is mainly obtained through direct elemental combination above 1000 °C, carbothermal reduction, and boron thermal reduction self-propagation. LaB6 has many applications in the electronics industry. Its field emission performance is better than that of W and other materials, and it has been widely used in electron microscopes. Current literature reports indicate that LaB6 has superconducting properties, but the temperature is very low, around 1K. Because LaB6 has many superior properties, such as strong electron emission, strong radiation resistance, and good high-temperature chemical stability. The material has a wide range of applications in the military and many high-tech fields, and can be used in many industries such as radar, aerospace, electronics industry, instrumentation, medical equipment, home appliances, metallurgy and so on. Among them, lanthanum boride single crystal is a good material for making high-power electron tubes, magnetrons, electron beams, ion beams, and accelerator cathodes.
