Lanthanum Hexaboride Disc, LaB6 Disc
Lanthanum Hexaboride (LaB6) disc is a ceramic disc made of a rare earth hexaboride compound, which has a high melting point and excellent thermionic emission properties. LaB6 discs are commonly used as electron emitters in various applications such as electron microscopy, X-ray generation, and electron beam lithography.
The LaB6 disc is typically manufactured by hot pressing or sintering LaB6 powder into a dense, uniform disc shape. The resulting disc has a smooth surface and a high degree of purity, ensuring consistent and reliable electron emission over extended periods of use.
LaB6 discs are available in various sizes and thicknesses and can be customized to meet specific application requirements. They are widely used in scientific research, industrial manufacturing, and medical imaging, among other fields.
