Abstract:
1. A silicon carbide-based porous body that is a honeycomb structure having porous partition walls forming a plurality of cells, which act as fluid passages, by surrounding the cells with the partition walls, the porous body comprises a plurality of silicon carbide (SiC) particles as an aggregate and a binder which binds the silicon carbide particles to each other, wherein the content of the binder relative to the total of the binder and the silicon carbide particles is 15 to 40% by volume, the open pore ratio is 30 to 70%, and the binder contains at least one metal disilicide in an amount of at least 80% by volume of total binder, any remainder of the total binder being made up of silicon, the at least one metal disilicide being selected from the group consisting of a Ti disilicide, a Zr disilicide, a Mo disilicide and a W disilicide.
