The Ceramic Ignition Pin is a critical component of ignition systems for gas-fired equipment. It is constructed using high-purity alumina (Al₂O₃) ceramic as the primary insulating material, combined with a high-temperature resistant alloy electrode. Widely used in applications such as gas stoves, gas water heaters, wall-hung boilers, industrial burners, ovens, and biomass boilers, this product ensures safe, efficient, and reliable ignition.
Alumina Ceramic Igniter Pin for Global Gas Equipment Manufacturer
Product Description
Renowned for its exceptional high-temperature resistance, superior insulation, thermal shock resistance, and long service life, the alumina ceramic ignition electrode has become the preferred choice for modern gas ignition systems. Whether for daily cooking on household stoves or continuous, high-intensity operations in industrial burners, our electrodes deliver a safe, reliable, and efficient ignition experience. We welcome inquiries regarding custom solutions and are committed to supporting your equipment with professional expertise and premium service. Our products support full-dimension customization and one-stop component manufacturing; the seamless, integrated structure eliminates common industry issues associated with split-design ceramics—such as breakage and electrical leakage failures. Offering a longer lifespan and a higher safety margin compared to standard low-alumina ceramic parts, they are the ideal high-voltage ignition insulation component for global gas equipment manufacturers.
Product Advantages
Core Materials and Manufacturing Processes
1. Ceramic Insulator
Material: 95%–99% high-purity alumina ceramic (Al₂O₃)
Manufacturing Process: formed via hot-pressure slurry casting and sintered at 1,500°C; surface can be treated with high-temperature glaze
Characteristics: dense structure, translucent appearance, high hardness (Mohs scale 9), wear resistance, and corrosion resistance
2.Electrode Pins
Common materials: Ni80Cr20 (nickel-chromium alloy), 0Cr25Al5 (iron-chromium-aluminum alloy), Cr27Al7Mo2, Kanthal (Kanthal A1 withstands temperatures up to 1400°C), or SUS304 stainless steel
Temperature resistance range: 1100°C–1500°C; certain special alloys can withstand temperatures exceeding 1600°C
Surface treatment: Titanium surface treatment to enhance oxidation and corrosion resistance
3.Connection Components
Plug: brass; ensures sensitive signal transmission and excellent thermal conductivity.
Cable: UL-certified high-temperature cable (e.g., UL1332, UL3573, UL3257); temperature resistance up to 250°C.
Mounting Method: threaded connection (M14×1.25, M16×1.5, M18×1.5, G1/2, etc.) or snap-fit connection; ensures easy installation/removal and a secure connection.
Product Features
| Characteristic | Detailed Description |
| Ultra-high Temperature Resistance | the ceramic body withstands high temperatures of 1200°C–1700°C for extended periods, while the electrode pin withstands 1100°C–1500°C; neither softens, deforms, nor suffers performance degradation in extreme flame environments. |
| Superior Insulation | breakdown voltage ≥15–20 kV/mm; maintains excellent electrical insulation properties even at high temperatures, effectively preventing current leakage and arc breakdown. |
| Thermal Shock Resistance | low coefficient of thermal expansion; capable of withstanding repeated thermal cycling (heating–cooling–reheating) without cracking or embrittlement. |
| High Mechanical Strength | flexural strength ≥350 MPa, compressive strength ≥2050 MPa; impact-resistant and wear-resistant; suitable for various installation environments. |
| Chemical Stability | resistant to acid and alkali corrosion and oxidation; the high-temperature surface glaze further prevents carbon buildup and chemical erosion. |
| Safe and Reliable | features built-in grounding protection and automatically stops discharging if the gas supply is interrupted to prevent gas accumulation; complies with international certification standards such as UL, CE, and RoHS. |
Technical Specifications
| Item | Detailed Specifications |

| Molding Process | dry-press molding and high-temperature integral sintering; no adhesive bonding or splicing; precision-machined internal threaded bore. |
| Standard Size (customizable) | base features a double-step flange with an overall outer diameter of φ20–φ40 mm; ceramic rod outer diameter of φ6–φ16 mm; total rod length of 20–80 mm; internal thread (standard metric M3/M4/M5/M6) with a thread depth of 5–15 mm. |
| Machining Accuracy | outer diameter tolerance ±0.005 mm; total length tolerance ±0.01 mm; thread coaxiality ≤0.02 mm; flange face flatness ≤0.008 mm. |
| Surface Treatment | available in mirror-polished or matte-ground finishes; free of air pockets, sand holes, and cracks. |
| Matching Accessories | offers a one-stop solution compatible with metal electrodes, springs, conductive pins, and silicone sealing gaskets. |
| Production Model | standard stock items plus OEM/ODM custom mold development; manufacturing based on provided drawings or samples is supported. |
Application Areas
Installation and Maintenance Recommendations
1. Installation: secure using standard threads or a snap-fit mechanism; no specialized tools are required, and installation can be completed within 5 minutes. Pls ensure the electrode gap meets equipment specifications (typically 3–5 mm).
2. Testing: periodically check resistance using a multimeter (normal range: 40–200 Ω); infinite resistance indicates electrode failure.
3.Cleaning: regularly remove carbon deposits from the electrode tip and prevent oil accumulation; inspect the ceramic body for cracks or white residue.
4.Replacement Interval: service life is 3–10 years under normal operating conditions; annual inspections are recommended for harsh operating environments.
