    MgO Substrates

    Purity and Uniformity:

    The MgO crystals used in our substrates exhibit exceptional purity, ensuring consistent performance across the entire product range.

    Microscopically, the majority of MgO crystals have a grain size of at most 5 μm, ensuring a uniform microstructure that enhances overall reliability.

    Electrical Insulation:

    With an electrical insulation resistance of at least 10^10 Ω·cm at 300°C, our MgO Substrates are ideal for electrically insulating applications.

    The ceramics have a dielectric constant of at most 10 at 100 kHz, making them suitable for high-frequency circuits and devices.

    Thermal Conductivity:

    The substrates boast a heat conductivity of at least 0.08 cal/cm·sec·°C at normal temperature, allowing for efficient heat dissipation in demanding environments.

    Resistance to Humidity:

    The MgO ceramics used in our substrates demonstrate excellent resistance to humidity, ensuring long-term stability and reliability in various climate conditions.

    Surface Finish:

    Both sides of the substrates are polished to a surface roughness (Ra) of ≤ 0.5 nm, providing a smooth surface for high-precision applications.

    Applications: Optical Devices, High-Temperature Superconductors, Magneto-Optic Films, THz Band Generators/Receivers, Semiconductor Processing, etc.
