| titleOfInvention | Method for making porous mullite-containing composites |
| abstract | Porous composites of mullite and cordierite are formed by firing needle-shaped mullite bodies in the presence of a magnesium source and a silicon source. In some variations of the method, the magnesium and silicon sources are present at the needle mullite body formation. In another variant, a magnesium source and a silicon source are applied to a previously formed needle bed mullite body. Surprisingly, the composite has a linear thermal expansion coefficient that is a value between the linear thermal expansion coefficient of mullite and cordierite alone, and has a fracture strength higher than that of cordierite of similar porosity. Some of the cordierite form crossing points and / or grain boundaries between mullite needles rather than simply coating the mullite needles. The presence of magnesium and silicon sources during needle bed mullite formation does not significantly affect the ability of the mullite needles to produce highly porous networks. |
