CE1848 Cerium Hexaboride Cathodes(CeB6/CeBix cathodes)

Cerium Hexaboride Cathodes Description

Cerium Hexaboride Ceramic Part is often fabricated through processes like sintering, where the powdered cerium hexaboride is compacted and heated to form a dense, solid ceramic structure. Tailored for technological applications demanding high-performance electron emission, this ceramic part excels in delivering reliable and efficient electron beams. Cerium Hexaboride Ceramic is known for its high brightness, contributing to the intensity of the electron beam produced. High brightness is essential for achieving better resolution in electron microscopy.

Cerium Hexaboride Ceramic Part FAQs

Q1: What is cerium hexaboride (CeB6) used for in cathodes?

Cerium hexaboride is widely used as a thermionic electron emitter in electron microscopy, electron beam welding, and other vacuum applications due to its low work function and high electron emission efficiency.

Q2: What are the advantages of using cerium hexaboride cathodes?

CeB6 cathodes offer excellent electron emission properties, including low work function, high current density, and stability under high temperatures and in vacuum environments. They are also resistant to contamination.

Q3: What are the operating conditions for cerium hexaboride cathodes?

CeB6 cathodes operate in high vacuum environments, typically at temperatures ranging from 1000°C to 2000°C. They require a clean and stable vacuum to maintain optimal performance.
