Which materials can prepare honeycomb ceramics?
The materials for preparing honeycomb ceramics include cordierite, aluminum titanate, spodumene, zircon, silicon carbide, silicon nitride, mullite. Among them, cordierite (2MgO·2Al2O3·5SiO2) honeycomb ceramics have the characteristics of good matching with various catalyst active components, thin pore walls, large specific surface area, and small thermal expansion coefficient, so cordierite honeycomb ceramics are the most widely used.
Where is the core technology of honeycomb ceramic preparation displayed?
The core technology of honeycomb ceramic preparation is mainly embodied in the control of thermal expansion coefficient, wall thickness, and pore density. There are very high requirements on the purity and proportion of raw materials, molding die, extrusion process, and sintering process.
