Magnesium Oxide (MgO) Single Crystal Substrate Description
Magnesium Oxide (MgO) Single Crystal Substrate is widely used in many thin film technology fields. For example, it is used to make magnetic thin films, semiconductor thin films, optical thin films, and high-temperature superconducting thin films. The dielectric constant and loss of MgO single crystal in the microwave band are very small. Magnesium Oxide (MgO) Single Crystal Substrate is a large area substrate, and it is one of the important high-temperature superconducting thin film single crystal substrates for current industrialization. It can be used to make high-temperature superconducting microwave filters and other devices required for mobile communication equipment.

Magnesium Oxide (MgO) Single Crystal Substrate Packaging
Our Magnesium Oxide (MgO) Single Crystal Substrate is carefully handled during storage and transportation to preserve the quality of our product in its original condition.
Q1: What is a Magnesium Oxide (MgO) single crystal substrate?
A Magnesium Oxide (MgO) single crystal substrate is a material composed of magnesium and oxygen atoms arranged in a crystalline structure. It is commonly used as a substrate for the epitaxial growth of thin films in electronic, optical, and magnetic applications.
Q2: How are MgO single crystal substrates typically prepared?
MgO single crystal substrates are typically prepared using the Czochralski (CZ) method or by using a high-temperature flux growth method. These methods involve melting high-purity magnesium oxide and then slowly cooling it to form a single crystal.
Q3: How should MgO single crystal substrates be stored and handled?
Storage: Store in a clean, dry environment to prevent contamination.
Handling: Use gloves and handle with care to avoid introducing surface defects or contamination.
