Honeycomb ceramic is used as a carrier in a three way catalytic converter for automobileindustry with its special large surface area. The product can load enoughnoble metal and other catalytic reactive components, making the Carbon Monoxide(CO), Hydrocarbons (HC), Nitrogen Oxides (NOX) in car exhaust emitted after purifying.Meanwhile, the wall-flowing type of filter with porosity and thin wallis able to filter particulates in the diesel exhaust gas (about 500°C).Specifications: 1) Material: cordierite2) Shape of channels: square 3) Number of channels (cells/in2): 4004) Distance of channels (mm): 1.275) Thickness of wall (mm): 0.186) Cell-opening ratio (%): 787) Loose density (g/cm³): 0.418) Geometric superficial (mm²/mm³): 26.89) True density: 2.010) Particle mesa-position aperture (μm): 4 - 1011) Coefficient of water absorption: normal temperature (Wt%): 15 - 1812) Coefficient of thermal expansion (40 - 800°C) x 10-6/°C: 12.0; B axis(MPa): >1.4 producing area:China payment:T/T, irrevocable L/C at sight
