Ceriumhexaboride Rod Description
Ceriumhexaboride rods undergo a precise manufacturing process, predominantly sintering. In this process, powdered cerium hexaboride is compressed and heated, which produces a dense, solid ceramic structure that retains the defined properties of cerium hexaboride. This ceramic component was developed for technological applications that require high electron emission performance and produces reliable, efficient electron beams. It is known for its high brightness and significantly increases the intensity of the produced electron beam, thereby contributing to achieving resolution that fulfils technical requirements in electron microscopy.
