zhiyuematerial on 24 Mar 25Lanthanum hexaboride is a rare boride formed by the combination of rare earth element lanthanum and non-metallic element boron. It presents in the form of purple powder, insoluble in water and hydrochloric acid, but has many remarkable characteristics: high melting point, high hardness, good chemical stability, excellent resistance to intermediate toxicity, long service life, and low electron escape work. These characteristics make lanthanum hexaborate shine in the field of cathode emission materials, especially in the manufacturing of high-precision and cutting-edge instruments such as electron microscopes, high-power electron tubes, electron guns, magnetrons, etc. In addition, lanthanum hexaborate is widely used in various military and high-tech fields such as radar aerospace, electronic industry, instrumentation, medical equipment, home appliance metallurgy, and environmental protection.
