Advanced ceramics, with their high-temperature resistance, corrosion resistance, high insulation, super hardness and wear resistance, have broken through the limits of traditional materials and become the "performance customizer" in high-end manufacturing, energy, medical and other fields. Through the design of composition and structure, they can simultaneously meet the diverse demands of extreme environments in aerospace, nanometer precision in 5G communication, and long-term compatibility in biomedical applications, achieving "one material, multi-scenario empowerment". Their value is not limited to a single application, but lies in promoting the synchronous technological upgrade of multiple industries through material innovation.

○ Burner Caps/Flame Spreaders : Burner caps made fromcordierite (2MgO·2Al₂O₃·5SiO₂) or silicon carbide (SiC)ceramics feature an extremely low thermal expansion coefficient, withstanding severe thermal cycling without cracking. This ensures even flame distribution and eliminates the clogging issues associated with long-term rusting of cast iron caps.
○ Infrared Radiant Panels :Porous silicon carbide (SiC) ceramic panelsare used in high-efficiency gas cooktops and commercial heating appliances. The tens of thousands of micro-pores on their surface enable flameless combustion of premixed gas and air, converting thermal energy directly into infrared radiation. This boosts thermal efficiency to over 70%, significantly higher than the 50-55% of traditional open-flame combustion.
○ Oven Furnace Heating Elements :Metallized ceramic heating tubes(e.g., alumina tubes) are widely used in commercial baking equipment. The ceramic substrate provides excellent electrical insulation and high-temperature strength, with built-in resistance wires enabling rapid heating above 800°C for a stable, uniform baking heat source, lasting 3-5 times longer than traditional metal heating elements.

○ High Efficiency Precise Ignition : Ceramic igniters generate a discharge voltage of 12-20 kV, producing concentrated sparks that can ignite gas within 0.1 seconds. Their response speed far surpasses mechanical ignition and supports intelligent safety features like flame failure protection.

○ Safety Stability : The inherent high insulation (volume resistivity10¹² Ω·cm) and non-combustibility of ceramic materials fundamentally eliminate risks of electric leakage, short circuits, and self-ignition, forming the cornerstone for the safe operation of gas appliances.
○Energy Saving Environmental Protection : Technologies like porous ceramic infrared combustion significantly reduce emissions of carbon monoxide (CO) and nitrogen oxides (NOx) through complete combustion. CO emissions can be lowered to below 0.01%, while the substantial improvement in thermal efficiency directly reduces gas consumption.
