<p>A porous material (1) wherein silicon carbide particles (2) as an aggregate are bound with one another via silicon nitride (3) as a binding material in such a state that pores (5) are present between silicon carbide particles (2), characterized in that no cylindrical-shaped silicon nitride(silicon nitride whisker) is formed on the surface of the silicon nitride (3) within the pore (5), or that, even when silicon nitride whisker is inevitably formed there, the number of such silicon nitride cylinders having a thickness of more than 2 mum and an aspect ratio of less than 10 is greater than that of such silicon nitride cylinders having a thickness of 2 mum or less or an aspect ratio of 10 or more; a method for prepare the porous material; and a honeycomb structure comprising the porous material.</p> |
