Magnesium oxide purity 95% MgO film substrate 5x5 10x10 20x20 thickness 0.5mm 1.0mm orientation <001> <110> <111>
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.
