Abstract:
1. A method of manufacturing a ceramic honeycomb structural body, which comprises mixing silicon carbide raw powders, mixing it to prepare ceramic powder raw materials, molding the resulting ceramic powder raw materials into a honeycomb pillar shape, and firing it to form a sintered body, wherein said silicon carbide raw powders are comprised of about 60 to about 80% by mass of particles belonging to a first particle group having a particle size of 1.0 μm to about 100 μm, and about 20 to about 40% by mass of particles belonging to a second particle group having a particle size of about 0.1 μm or more and less than 1.0 μm in which the particles of the first particle group has one frequency peak in a particle size distribution curve wherein an abscissa is a particle size (μm) and an ordinate is a frequency (%) and satisfy the following relationship: wherein D D D
