  • Summary

Intruduction

Sinton’s silicon nitride igniters are normally rectangular in shape. These igniters have a lot operation zone up to 1000 degree C . and a cold zone in the contact area. Encapsulated terminal can prevent short circuit caused by conductive contamination. They can be operated with or without a controller. Silicon nitride igniters have several times the durability than that of silicon carbide products.

Dimension , power and input voltage are customizable according to your requirement.

Silicon Nitride igniter can heating up to 800 to 1000degree within tens of seconds. Silicone Nitride ceramic can sustain corrosion of melting metals. With proper instatllation and igniting process , the igniter can server several years.
