Electrical Properties Of Silicon Nitride

Electrical insulating

silicon nitride is a good electrical insulator with a resistivity of up to 10¹⁴ Ω·cm, which retains excellent insulating properties even at high voltages. This property of silicon nitride makes it widely used in the electronics industry, where it can be used to make insulating parts of electrical equipment, such as high-voltage circuit breakers and high-frequency circuits, to prevent current leakage or short circuits.

Dielectric properties

Silicon nitride has a dielectric constant between 7.5-8.5 and low dielectric loss, making it ideal for high-frequency and microwave applications. This feature makes silicon nitride excellent in high-frequency circuits and microwave antennas, ensuring stable signal transmission and preventing electromagnetic interference from affecting the performance of the device. Silicon nitride materials are used as the main material in many communications and high-frequency electronic components to ensure the reliability of equipment in high-frequency environments.
