Abstract:
A porous material and preparation method thereof is provided. The material includes a material body. The body consists of pore cavities classified according to pore size of material and cavity walls surrounding to form the pore cavities. The lower-level pore cavities are arranged on the cavity walls of the upper-level pore cavities framed by surrounding a three-dimensional space. All the pore cavities are interconnected. The preparation method is: mixing raw powders with pore-forming agent for the smallest-level pore cavities of porous material to formulate slurry; uniformly filling the slurry into polymer material support to form green body and get dried and smashed to obtain mixed grains; uniformly mixing the mixed grains with pore-forming agent for upper-level pore cavities greater than the smallest-level pore cavities of porous material to make compact green body; performing vacuum sintering; performing the conventional follow-up treatment according to the raw materials process of porous material.

Claim (Index 13):
The porous material according to  claim 11 , wherein the porous non-metal material is one or more selected from the group consisting of ceramic materials, high siliceous silicate materials, aluminosilicate materials, diatomaceous earth materials, pure carbonaceous materials, corundum and diamond.
