Place of Origin:Guangdong, China
Material Introduction:
The ignition element is made from silicon nitride ceramic (Si₃N₄) and is supplied with high-temperature lead wires and a connection terminal.
Functional Features:
Fast heat-up allows the igniter to reach ignition temperature quickly. The silicon nitride heating tip offers good high-temperature stability and thermal shock resistance for repeated ignition and heating cycles.
Application Industries:
Suitable for gas boilers, gas water heaters, pool heating equipment, industrial burners, commercial gas appliances and other combustion systems. View more ceramic igniters.
Global OEM Supply:
Serving OEM customers in the USA, Germany, Japan, and Europe. Product configurations can be matched to equipment interfaces, operating voltage, lead-wire requirements and mounting structures.
Lead Time:
Lead time depends on product specifications, connection design, order quantity and testing requirements. The delivery schedule for standard or customized models will be confirmed after the technical details are reviewed.
This silicon nitride hot surface igniter combines a Si₃N₄ ceramic heating tip with high-temperature lead wires and an electrical connector. It is designed for gas furnaces, gas water heaters, pool heating equipment and industrial burners. Once energized, the heating tip quickly reaches fuel ignition temperature, helping reduce ignition delays, repeated start attempts and unstable burner start-up.
The heating tip is made from silicon nitride ceramic (Si₃N₄). It is assembled with an insulated connection structure, high-temperature lead wires and electrical terminals to form a complete hot surface igniter.

| Comparison | Silicon Nitride Hot Surface Igniter | Silicon Carbide Igniter | Alumina Ignition Electrode |
|---|---|---|---|
| Ignition Method | Direct heating through a ceramic tip | Direct heating through a ceramic element | Usually produces a spark through high-voltage discharge |
| Heat-Up Response | Fast | Fast | Not a resistance-heated ignition element |
| Thermal Shock Resistance | Good | Suitable for high temperatures but generally more brittle | Mainly provides insulation and electrode support |
| Mechanical Strength | Good | Generally lower | Depends on alumina purity and component structure |
| Typical Applications | Gas furnaces, water heaters and industrial burners | Stoves, pellet heating equipment and industrial heaters | Boilers, burners and spark ignition systems |
| Selection Factors | Voltage, power, dimensions and control method | Voltage, element shape and mounting conditions | Spark gap, insulation performance and electrode material |
The appropriate igniter should be selected according to the ignition method, equipment voltage, start frequency, installation space and operating environment.
A silicon nitride hot surface igniter is a ceramic ignition component that heats rapidly when energized. Its high-temperature tip ignites gas or another suitable fuel in an automatic combustion system.
Typical applications include gas furnaces, natural gas furnaces, gas water heaters, pool heating equipment, boilers, industrial burners and other combustion systems.
No. This product is intended for hot surface ignition in combustion equipment. A diesel glow plug is mainly used for cold starting engines or parking heater systems. Their voltage, structure and connection interfaces are usually different.
Replacement suitability must be evaluated using the original ignitor voltage, power, heating-tip dimensions, control method and mounting position. A 120V model cannot be directly replaced by a 230V model. Please provide the original part number, drawing or physical sample for review.
Please provide the equipment type, operating voltage, rated power, required ignition time, heating-tip dimensions, lead-wire length, connector type, mounting structure and estimated order quantity. Lead wires, connectors and mounting arrangements can be evaluated against the equipment interface.
Yes. We serve OEM customers in the USA and also support projects in Germany, Japan and Europe. Drawings, samples and equipment interfaces can be reviewed before quotation.
Lead time depends on the product specifications, connection structure, testing requirements and order quantity. The delivery schedule for standard and customized models will be confirmed after the technical details have been reviewed.
To select or replace a silicon nitride hot surface igniter, please send the original ignitor model, equipment type, operating voltage, rated power, heating-tip dimensions, lead-wire length, connector, mounting structure and required quantity. We will review the information and provide a suitable quotation.
