Engineering Excellence in Cordierite-Mullite Composition

Our Cordierite-Mullite ceramic honeycomb blends the best of both materials to deliver outstanding performance. Cordierite’s low thermal expansion means it handles rapid temperature changes without cracking—perfect for extreme thermal shock resistance. Mullite adds high strength and creep resistance, keeping the honeycomb stable even at temperatures up to 1700°C.

Together, these crystal phases balance durability and longevity, with a combined coefficient of thermal expansion (CTE) carefully engineered to stay below 16×10⁻⁷/°C across a wide temperature range. This means the honeycomb substrate expands and contracts evenly, avoiding stress and extending service life.

Honeycomb Geometry and Surface Area

The unique honeycomb structure features precise cell counts per square inch (CPSI), ranging from 50 to 600 CPSI, designed to maximize surface area for catalytic reactions or heat exchange. This translates to over 2,000 square meters of active surface area per cubic meter, boosting efficiency in applications like catalytic converters and regenerative thermal oxidizers (RTO).

The geometry also affects flow dynamics—optimized cell shapes and wall thickness help reduce backpressure and improve fuel efficiency in automotive uses.

Property	Gotrays Cordierite-Mullite	Silicon Carbide Alternative
Thermal Shock Resistance	High	Moderate
Operating Temperature	Up to 1700°C	Up to 1400°C
Flexural Strength	>100 MPa	~80 MPa
Density	2.5-2.8 g/cm³	3.1-3.2 g/cm³
Porosity	30-50%	15-25%

This spec matrix shows why Gotrays’ honeycomb is a top choice for emission control and thermal applications in the United States, where durability, efficiency, and regulatory compliance are non-negotiable.

FAQ What CPSI Works Best for Diesel vs Gasoline

• Diesel Engines: Higher cell densities (400-600 CPSI) improve filtration for diesel particulate filters, capturing more soot and particulates.
• Gasoline Engines: Lower CPSI (100-300) helps reduce backpressure while efficiently converting CO, NOx, and HC in catalytic converters.
• Custom Solutions: Gotrays tailors CPSI options to your specific needs for the best balance of performance and longevity.
