Why choose Silicon Nitride Heaters from GORGEOUS?

GORGEOUS Silicon Nitride Heater Core Advantages

Fast Heating, High Power Density
Silicon nitride ceramic’s excellent thermal conductivity (approximately 20–30 W/m·K, significantly higher than alumina’s 15–25 W/m·K) allows it to reach operating temperature in a very short time.
Its surface power density can reach 10–20 W/cm², 3–5 times higher than traditional metal heating elements, helping you achieve rapid heating and efficient heat transfer.

Small Size and Compact Structure
For the same heating output, our silicon nitride heaters are 30–50% smaller than traditional metal or alumina heating elements, making them ideal for applications with limited space.

Ultra-Long Service Life
Our heaters can withstand rapid cooling and heating cycles exceeding 500°C without cracking. Their continuous operating life typically exceeds 10,000 hours.

High Insulation and Safety
Silicon nitride boasts an insulation resistance of >10⁷ Ω·cm, maintaining stable insulation performance even at temperatures of 1000°C. The risk of electrical leakage is extremely low, ensuring safe operation.

Can directly heat water, oil, and other liquids.
Can be directly immersed in liquid media such as water, kerosene, and diesel.

Basic Structure of Silicon Nitride Heater

GORGEOUS’s ceramic heaters feature an integrated heating element design. During the manufacturing process, the heating element is embedded directly into the ceramic substrate and sintered integrally through a high-temperature co-firing process.

The advantages of this integrated structure are as follows:

  • Complete isolation from external air—the heating element is encased in dense ceramic, preventing oxidation or moisture from damaging it.
  • Multiple circuits can be integrated—multiple circuits can be integrated into the same substrate, enabling flexible output switching.
  • Intelligent monitoring—an embedded temperature sensor (such as a thermocouple or PT100) can be used for precise real-time temperature monitoring and closed-loop control.
