Cerium Hexaboride Sheet Applications

1. Thermionic Emitters in Large-Area Devices: CeB6 sheets can be used as thermionic emitters in large-area devices where a uniform electron emission is required across a broad surface. This is particularly useful in devices such as electron beam lithography systems and large-scale electron microscopes.

2. X-ray Generation: In some advanced X-ray systems, CeB6 sheets can be used as cathode materials for generating X-rays, especially in applications that require a larger emission area or uniformity across the surface.

3. High-Temperature Coatings: CeB6 sheets can serve as high-temperature coatings or liners in furnaces and other high-temperature environments, where their stability and resistance to oxidation protect underlying materials from thermal degradation.

4. Vacuum Electronics and Plasma Devices: In vacuum electronics and plasma generation devices, CeB6 sheets can be used as electron sources, particularly in systems that require large, flat-emitting surfaces, such as certain types of plasma displays or large-area field emission devices.

5. Ion Thrusters: While more commonly associated with rods or discs, CeB6 sheets can be utilized in ion thruster designs where a larger surface area is needed for uniform electron emission to help generate and sustain the plasma.

6. Research and Development: CeB6 sheets are used in research and development for studying high-temperature materials, thermionic emission properties, and surface science, providing a flat, uniform surface for controlled experiments.

7. Field Emission Displays (FEDs): In field emission displays, CeB6 sheets can be used as electron-emitting cathodes, offering a uniform and stable electron source across a large display area.

8. Surface Engineering: CeB6 sheets may be employed in surface engineering applications where their high temperature and oxidation resistance are beneficial, potentially as part of composite materials or as a substrate for other high-performance coatings.
