Cerhexaborid Disc Description
The Cerhexaborid disc undergoes a meticulous manufacturing process. It is primarily sintered, during which powdered Cerhexaborid is compressed and heated. Consequently, this process produces a dense, rigid ceramic structure that preserves the defined properties of Cerhexaborid. The component is designed for technological applications that require efficient electron emission. It produces reliable electron beams and increases beam intensity. The disc is known for its high brightness; this improvement is critical for achieving enhanced resolution in electron microscopy.
