Honeycomb ceramic carrier

● Honeycomb ceramics as a carrier is the key part of three-way catalytic converters. The honeycomb structure with thousands of parallel channels forces the exhaust gas into a turbulent state, resulting in more Good exhaust effect The contact between emissions and precious metals improves the mass transfer conditions and improves the conversion efficiency.Therefore the cordierite ceramic honeycombs have been developed as substrates for automotive catalytic converters to solve the environmental pollution problems.
