Beryllium Oxide Ceramic Bar Rod
The beryllium oxide (BeO) is a ceramic material with high conductivity and low dielectric constant, which makes it widely used in the field of electronic technology, such as special metallurgy, vacuum electronic technology, nuclear technology, microelectronics and photoelectron technology due to its high thermal conductivity, high insulation, low dielectric constant, low medium loss, and good process adaptability.
Beryllium Oxide Ceramic Feature:
1.Superior Thermal Conductivity
2.More Consistent Heat Dissipation
3.Better Uniformity of Crystalline Structure
4.Easy and Effective Metallization
5.More Durable in Semiconductor Chamber Cleaning Environments
