Part Number | SB12 |
Purity | 99.95% |
Density | 3.58 g/cm3 |
Synonyms | Single Crystal MgO Substrate, MgO Substrate |
Magnesium oxide single crystal is made of high-purity MgO, produced in the process of producing high-purity fused magnesia. MgO purity is more than 99.90%, with bulk density more than 3.5 g/cm3. It is a colorless and transparent crystal with strong high and low temperature resistance (high temperature 2500°C, low temperature -270°C), excellent thermal conductivity and optical properties. It is widely used in making ferroelectric films, magnetic films, optical films and high temperature superconducting films, etc. Get a Quote Now!

Typical application:
Magnesium oxide (MgO) single crystal substrate is widely used in many film technology fields. For example, it is used to make magnetic films, semiconductor films, optical films and high temperature superconducting films. The dielectric constant and loss of MgO single crystal in the microwave band are very small and it can get a large area of substrate (diameter 2 inches and larger). As a result, it is one of the most important high-temperature superconducting film single crystal substrates in current industrialization. It can be used to make high temperature superconducting microwave filters and other devices for mobile communication equipment. It has a large practical and potential application market.
