POROUS CELLULAR STRUCTURES OF AMORPHOUS FUSED SILICA GLASS AND METHOD OF THEIR MAKING

摘要

A porous cellular body comprising primarily a porous sintered glass material is disclosed. The porous sintered glass material primarily includes a first phase and a second phase, the first phase primarily comprising amorphous fused silica and the second phase comprising amorphous fused silica and a sintering aid. A method of making the porous cellular body is also disclosed, whereby a precursor batch of amorphous silica and sintering aid is extruded to form a green cellular body, which is heat treated to render porous.
