T/TThe ceramic spark plug is a critical automotive/engine component that uses a high-performance ceramic insulator (typically alumina ceramic) to isolate the central electrode from the metal shell. It generates an electric spark to ignite the air-fuel mixture in internal combustion engines (gasoline, LPG, or natural gas), ensuring efficient combustion, stable engine operation, and reduced emissions.

Alumina ceramic pipes are widely used in industries where traditional metal/plastic pipes fail to withstand wear, corrosion, or high temperatures. Abrasive Slurry Transport: Mining & Mineral Processing: For transporting tailings, mineral concentrates, and sand. Coal-Fired Power Plants: For conveying fly ash and bottom ash slurries. Steel Industry: For dust and fume extraction systems. Corrosive Chemical Handling: Chemical Plants: As liners or full pipes for aggressive acids and alkalis. Laboratory Equipment: For high-purity or high-temperature gas and fluid delivery. High-Temperature Applications: Thermocouple Protection Tubes: To shield temperature sensors in furnaces and kilns. Industrial Furnaces: As radiant tubes or for transporting hot gases. Welding Torch Nozzles: For their electrical insulation and heat resistance. Electrical Applications: Insulating Bushings and Sleeves: Where a pipe must provide a barrier that is both mechanically strong and electrically insulating.
