Lanthanum hexaboride ( LaB6 ) is an inorganic compound with remarkable properties. It is a refractory ceramic material, characterized by a dark purple appearance, a high melting point of 2210°C, and excellent stability in both vacuum and harsh chemical environments—it is insoluble in water and hydrochloric acid. Known for its low work function, LaB6 exhibits one of the highest electron emissivities, making it a highly efficient electron source.   LaB6 cathodes are high-performance, resistively heated thermionic electron emitters. Over the years, LaB6 hollow cathodes have demonstrated exceptional durability and reliability in electric propulsion systems. Hollow cathodes, which utilize materials with low work functions to efficiently emit electrons, are complex devices. LaB6 hollow cathodes with polycrystalline inserts are particularly well-suited for such applications due to their favorable properties.     Lanthanum Hexaboride Cathodes Advantages: Extended lifespan Excepti...

  LaB6 Ceramic  is an inorganic non- metallic compound composed of low-valence boron and the rare metal element lanthanum. It is a refractory ceramic that could resist high temperature and harsh environments.  LaB6 ceramic  has lots of applications due to its ideal thermal, chemical, and electronic properties. As LaB6 ceramic has the characteristics of high emission current density and low evaporation rate at high temperature, it always work as a cathode material with superior performance and has gradually replaced some tungsten cathodes in industrial applications.   Features: 1. Excellent thermal shock resistance 2. Good electrical conductivity 3. Excellent chemical and oxidation resistance 4.High electron emissivities 5.Stable in Vacuum   Applications: • Scanning Electron Microscopes • Transmission Electron Microscopes • Electron Micro Probe Analy...
