Ceriumhexaboride Sheet Description
Ceriumhexaboride sheet is a component manufactured from Ceriumhexaboride (CeB6). It is known for its ability to emit electrons under heat treatment via thermionic emission. This sheet was designed to deliver reliable and efficient electron beams and is used in advanced technological applications that require high electron emission performance. The CeB6 sheet, valued for its thermionic properties, stability and capacity to achieve high brightness, enhances the resolution in electron microscopy.
