1. Definition and characteristics

Honeycomb ceramics are a porous ceramic material with a honeycomb-like structure. They are made of cordierite, silicon carbide, alumina and other materials through extrusion or hot die casting. Its core characteristics include:

High specific surface area: The number of pores per unit volume is extremely high (up to 40 pores per square centimeter), which significantly improves the catalytic efficiency.

High temperature resistance and thermal stability: Silicon carbide honeycomb ceramics can maintain strength at 1600°C, and the thermal expansion coefficient of cordierite material is as low as (0.67-1.8)×10⁻⁶/°C, which is suitable for extreme temperature environments.

Corrosion resistance and chemical stability: It can withstand acids, alkalis and organic solvents and is suitable for chemical reaction carriers.

Lightweight and high strength: The density is as low as 4-6 grams/cubic centimeter, the compressive strength is 280-500MPa, and it has structural support functions.

 Application fields

Environmental protection field

Automobile exhaust purification: As a three-effect catalyst carrier, it reduces CO, NOx and particulate matter emissions and meets the National VI standard.

Industrial waste gas treatment: used for flue gas denitrification (NOx) and catalytic combustion of volatile organic compounds (VOCs).

Energy field

Fuel cell: As a gas diffusion layer support material, it improves the efficiency of proton exchange membrane fuel cells.

Thermal management system: In new energy vehicle battery packs, the honeycomb structure is used to optimize heat dissipation and extend battery life.

Chemical and metallurgical

Catalytic cracking: Replaces traditional spherical catalysts and improves the conversion rate of heavy petroleum fractions.

Heat storage: Energy saving in heating furnaces is more than 40%, and the flue gas emission temperature is reduced to below 150°C.
