(2MgO·2Al₂O₃·5SiO₂) as a carrier material.\u003cbr\u003eCordierite: A ceramic material with a low expansion coefficient, it has excellent thermal stability and low cost characteristics and is currently the most commonly used carrier material for diesel vehicle DOC.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCharacteristics\u003c\/strong\u003e\u003cbr\u003e(1) Material characteristics\u003cbr\u003eHigh temperature resistance: It can withstand continuous high temperatures of 800~1000°C and withstand 1200°C for a short time (but long-term high temperatures may cause sintering failure).\u003cbr\u003eLow thermal expansion coefficient: The thermal expansion coefficient is low (~1×10⁻⁶\/°C), and the thermal shock resistance is good, avoiding cracking due to sudden temperature changes.\u003cbr\u003ePorous structure: The surface is coated with γ-alumina (γ-Al₂O₃) to increase the specific surface area and load precious metal catalysts such as platinum (Pt) and palladium (Pd).\u003c\/p\u003e\n\u003cp\u003e(2) Structural characteristics\u003cbr\u003eHoneycomb carrier: usually adopts a honeycomb structure of 400-600 CPSI (pores per square inch) to balance airflow distribution and back pressure\u003cbr\u003eLightweight: low density (about 2.0 g\/cm³), lighter than metal DOC.\u003c\/p\u003e\n\u003cp\u003e(3) Environmental adaptability\u003cbr\u003eChemical corrosion resistance: good tolerance to diesel sulfur content (under low sulfur fuel conditions), but long-term exposure to high sulfur environment may cause poisoning.\u003cbr\u003eModerate mechanical strength: more brittle than metal DOC, need to avoid severe vibration or
