Product Description

Beo Ceramic Ring Material Description:

Pure beryllium (BeO) belongs to the cubic crystal system. Density is 3.03g / cm3. Melting point is 2570 . It has a high thermal conductivity. Aluminum is almost equal with copper, thermal conductivity 200-250W / (mK), there is a good thermal shock resistance. Dielectric constant 6 ~ 7 (0.1MHz). Dielectric loss tangent value of about 4 × 10-4 (0.1GHz).

Beryllia ceramic with metallized:

Technology:using thick film  with electronic slurry.This technology could ensure that the surface is highly reliable to stick electronic factor.Adhesion of electrode and ceramic substrate is high, conductive performance of silver electrode is

excellent, and it is very easy to be welded.
