macor dielectric constant

Macor microcrystalline glass ceramic is an easy to process ceramic developed by Corning Inc. It has characteristics such as low dielectric constant and biocompatibility, and has a wide range of applications such as medical, aerospace, electronics, and other industries.

Dielectric constant

What is dielectric constant: The dielectric constant, also known as the dielectric constant or permittivity, is a physical quantity used to describe a material's response to an electric field. It represents the material's ability to store and conduct charges under the action of an electric field. The dielectric constant is usually represented by the letter ε, with a unit of F/m. But in vacuum, the dielectric constant is fixed, about 8.85 × 10 ^ -12 F/m.

The difference between high dielectric constant and low dielectric constant: The main difference between high dielectric constant and low dielectric constant lies in their response to electric fields, such as better charge storage in materials with high dielectric constant. This type of material has the ability to improve the energy storage effect of capacitors in integrated circuits. With the same size, it can increase the capacitance value. For materials with low dielectric constant, low dielectric constant can better reduce signal delay and crosstalk, improve the performance of integrated circuits, reduce losses during signal transmission, and improve transmission speed and efficiency. Therefore, it can better control the electric field, which is extremely important for improving the performance of integrated circuits.

Just now I mentioned the difference between high dielectric constant and low dielectric constant. The dielectric constant of Macor ceramics varies at different frequencies under the same temperature of 25 ° C. Typically, the dielectric constant at a frequency of 1000 Hz is 6.03, and at a frequency of 8.50e+9 Hz it is 5.67. The dielectric constant under different conditions is also different.

In the aerospace field, materials with low dielectric constant and low loss are required for high-frequency and high-speed transmission systems, engine components, and sensors. In space optics, materials such as mirrors and lenses can be used to improve the observation accuracy and performance on spacecraft. In the field of biosensors, its low dielectric constant and low loss are important for high-speed and high-frequency transmission systems on biosensors. In addition, its biocompatibility and corrosion resistance improve the sensor's detection of biomolecules, achieving zero density and precise capture of biological signals.

The low dielectric constant of Macor ceramics is particularly outstanding in high-frequency and high-speed transmission systems. Based on this characteristic, combined with its excellent electrical performance, it is an ideal choice for these industries, especially in the special environment of high frequency and high voltage, making it further applicable in a wide range of fields.
