Porous ß-SiC containing shaped ceramic body and method of making it.

摘要

Production of a porous ceramic shaped article (I) containing beta -silicon carbide (SiC) involves siliconizing a porous shaped article (II) containing carbon by incorporating a silicon source (III), selected from silicon and/or silicon-containing materials, in (II) and reacting the silicon and carbon components to give beta -SiC. Independent claims are included for: (1) porous ceramic shaped articles (I') containing beta -SiC, having a pervading 3-dimensional beta -SiC structure; and (2) systems containing (I').
