Honeycomb ceramic carrier, preparation method thereof and tail gas catalysis core body
The invention provides a honeycomb ceramic carrier, a preparation method thereof and a tail gas catalysis core body, the honeycomb ceramic carrier contains silicon carbide, the crystalline phase of the silicon carbide comprises 4H-SiC and 6H-SiC, the mass of the 4H-SiC accounts for 13%-30% of the total mass of the honeycomb ceramic carrier, the mass of the 6H-SiC accounts for 40%-55% of the total mass of the honeycomb ceramic carrier, the mass of the silicon carbide accounts for 10%-30% of the total mass of the honeycomb ceramic carrier, and the mass of the silicon carbide accounts for 10%-30% of the total mass of the honeycomb ceramic carrier. The porosity of the honeycomb ceramic carrier is 45%-70%, preferably 50%-65%. The honeycomb ceramic carrier provided by the invention has higher cost performance while ensuring better porosity, pore volume and thermal diffusion coefficient.
本发明提供了一种蜂窝陶瓷载体及其制备方法、尾气催化芯体，所述蜂窝陶瓷载体含有碳化硅，所述碳化硅的晶相包括4H‑SiC和6H‑SiC，所述4H‑SiC的质量占所述蜂窝陶瓷载体的总质量的13％～30％，所述6H‑SiC的质量占所述蜂窝陶瓷载体的总质量的40％～55％，所述蜂窝陶瓷载体的孔隙率为45％～70％，优选50～65％。本发明提供的蜂窝陶瓷载体能够在保证孔隙率、孔容、热扩散系数较佳的同时具有更高性价比。
