Al2O3 Spark Plug Ignition 95 Alumina Ceramic BBQ Engine Electrode Igniter

Product Description

Product Description

Alumina Ceramic Ignition Electrode

Our ignition electrode adopts high purity 95% alumina ceramic as insulating body, assembled with high temperature resistant wire and terminal connector. Custom ceramic dimension and wire length are available to match different burner models.

Gas Burner Igniter

The 95% alumina ceramic boasts density of 3.6 g/cm3 or higher, dielectric strength of 12 kV/mm or higher, and bending strength of 320 MPa or higher. It can bear continuous working temperature up to 1600 degree Celsius, with thermal expansion coefficient of 7.2 × 10(-6)/degree Celsius. The equipped high temperature wire resists thermal aging, maintaining steady spark output under repeated thermal cycles. Precise electrode gap ensures consistent spark generation for reliable ignition performance.

These technical parameters bring tangible advantages to manufacturers and end users. Dielectric strength of 12 kV/mm or higher delivers solid insulation performance and effectively prevents electric leakage and short circuit hazards. Bending strength above 320 MPa improves mechanical toughness, resisting cracks and breakage during installation, transportation and daily vibration. Stable operation at 1600 degree Celsius enables longt erm service in high temperature combustion environments. Its 7.2 × 10-6 /degree Celsius low thermal expansion coefficient keeps structural integrity under rapid temperature rise and fall, greatly cutting failure rate and product replacement cost. Pre assembled wire and terminals eliminate extra secondary processing work, helping customers improve assembly efficiency and shorten production cycles.

Alumina Ceramic Ignitor

This ignition electrode fits gas stoves, gas burners, commercial ovens, wall hung boilers and multiple gas fuel ignition devices. Both standard and OEM customized solutions are available.
