More info

Magnesium Oxide (MgO) Crystal Substrate is a high-quality single-crystal material used in the fabrication of ferroelectric, magnetic, optical, and high-temperature superconductor thin films. With a low dielectric constant and minimal microwave loss, it is ideal for electronic and optical applications. Available in large sizes up to two inches in diameter, MgO substrates are commonly used in high-temperature superconductor microwave filters for mobile communications. We also offer customized options to meet specific needs. Heeger Materials provides high-quality MgO Crystal Substrates for research and industrial applications.
