Description
Lanthanum Hexaboride (LaB₆) Micron Powder
Purity: 99.99%
Particle Size: 1–20 µm
Lanthanum Hexaboride (LaB₆), also known as lanthanum boride, is a refractory ceramic material renowned for its exceptional thermionic emission properties, low work function (~2.4 eV), and high chemical and thermal stability. Our high-purity LaB₆ micron powder (99.99%) with controlled particle size (1–20 µm) is ideally suited for advanced applications in high-temperature electron emission devices, X-ray diffraction calibration, and materials science research.
Due to its excellent electrical conductivity and high melting point, LaB₆ is widely used in hot cathodes, electron microscopes, and as a reference material in analytical instruments. It also finds utility in radar, aerospace, and infrared technologies where performance in extreme environments is critical.
