Product Description:
Thin film substrate magnesium oxide (MgO) single crystal is a
high-quality substrate material with excellent physical and
chemical properties, such as high melting point, low dielectric
constant and loss, good lattice matching, etc. It is widely used in
the manufacture of high-temperature superconductivity,
ferroelectric thin films, magnetic thin films and other thin film
technologies, and provides an ideal foundation for the growth of
high-quality thin films with its excellent stability and
transparency.

Features:
- Melting Point: Magnesium oxide single crystals have a melting point
of up to 2800°C, showing their excellent high-temperature
stability.
- Coefficient of Thermal Expansion: The coefficient of thermal
expansion is small, 2×10-6/°C, which helps to maintain the
stability of the material at high temperatures.
- Hardness: With a hardness of 5 on the Mohs scale, it is a
relatively hard material.
- Optical transmittance: It has good transparency in a wide
wavelength range, especially in the 200400nm and 5001000nm bands,
with optical transmittance exceeding 90% and 98% respectively.
- Chemical properties:Magnesium oxide single crystal has excellent
chemical stability and is not easy to react with other
substances.It also exhibits good electrical insulating properties
because there are no free electrons in its lattice structure and
its ability to conduct electric current is extremely low.

Applications:
Magnesium oxide (MgO) single crystals are used as thin film
substrates in a wide range of applications, and the following is a
clear description of their application areas:
- High-temperature superconducting films: MgO single crystals have
small dielectric constant and loss in the microwave band, and can
obtain large-area substrates (2 inches in diameter and larger),
making them 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, which is of great significance for
the commercial application of high-temperature superconducting
technology.
- Magnetic thin films: MgO single crystal substrates have excellent
physical and chemical stability, which is suitable for making
magnetic thin films.These magnetic films have a wide range of
applications in data storage, magnetic sensors, and more.
- Semiconductor thin films: As substrate materials for semiconductor
thin films, MgO single crystals can provide high-quality crystal
structures, which can help improve the performance of semiconductor
devices.It is widely used in the production of semiconductor
electronic equipment, such as capacitors, transistors, etc., to
ensure the working stability and reliability of components in
high-temperature environments.
