Mainstream process of honeycomb ceramics

Extrusion molding: plastic clay is extruded through a die, and micron-level pores are formed through microwave drying and high-temperature sintering (1280-1320℃).

Hot die casting: add surfactants such as paraffin, inject into the mold under pressure, and then degrease and sinter, which is suitable for complex-shaped products.

Formula of honeycomb ceramic materials

Cordierite: talc, clay, and alumina are mixed in proportion, and calcite is added to improve thermal shock resistance.

Silicon carbide: 5-10μm particle size ratio is adopted, and the thermal expansion coefficient is reduced by needle-shaped kaolin.

Block-Combined Honeycomb Ceramic Future Trends

Material innovation

Silicon nitride honeycomb ceramics: temperature resistance up to 1700℃, gradually replacing alumina for aerospace.

Composite materials: Silicon carbide fiber reinforced cordierite improves fracture toughness.

Intelligent manufacturing

Automated production line: Combine 3D printing technology to achieve customized pore structure.

Green manufacturing: waste recycling technology (such as preparing ceramic impellers from cordierite waste) reduces energy consumption by 20%.
