Silicon nitride heating element: a brief introduction of the original silicon nitride heating element


Release time:

2021-03-25

Through formulation improvement, process optimization and sintering process improvement, a new typesilicon nitride heating element

1、silicon nitride heating elementSmall size, light weight, high power density. Power> 100W/cm2, much higher than 2-8W/cm2 of ordinary metal heating body and 20-80W/cm2 of ordinary silicon nitride ceramic heating body.

2, through the development of molding and sintering technology process improvement, can be prepared to achieve a more complex shape for any temperature data distribution of silicon nitride ceramic heating body, such as cylindrical. Compared with the traditional sheet ceramic heating element, it has its own higher thermal efficiency and thermal shock resistance, and the service life of the product is greatly improved;

3. Excellent thermal performance. The heating efficiency is more than 98%, can reach 800-1000 ° c in a few seconds, can directly heat water, gas, kerosene, metal and other media, heating noise is small, no pollution;

4、silicon nitride heating elementHigh reliability.

A, high insulation material performance, leakage protection current <0.1mA during operation, far less than 2mA of the new national standard, leakage fault current <7mA after breaking, no breakdown experiment at 2500V for one minute at normal temperature;

B, superior mechanical properties, compressive and flexural strength, high hardness.

C,The resistance wire is not oxidized, broken, and not easy to age.

D, with excellent corrosion resistance, can be used in harsh environments, such as molten metal, chemical corrosion solution, etc.

E. After specific testing, the service life of the heater is>> 10,000 hours
