| 20080293564 | MULLITE BODIES AND METHODS OF FORMING MULLITE BODIES - A method of forming a porous mullite composition of acicular mullite grains having improved properties is described, where the mullite is formed at some time in the presence of a fluorine containing gas. For example, it has been discovered that improved properties may result from heating the mullite to a high temperature in an atmosphere selected from the group consisting of water vapor, oxygen, an inert gas or mixtures thereof or forming the mullite composition from precursors having an Al/Si ratio of at most 2.95. | 11-27-2008 |
| 20100104843 | ALUMINUM BORON CARBIDE COMPOSITE AND METHOD TO FORM SAID COMPOSITE - An improved aluminum-boron carbide (ABC) composite has been discovered that is comprised of a continuous network of AlB | 04-29-2010 |
| 20100304165 | MODIFIED GEOPOLYMER COMPOSITIONS, PROCESSES AND USES - The present invention relates to modified geopolymer compositions, geopolymer-coated organic polymer substrates, and methods of manufacturing and articles comprising same. | 12-02-2010 |
| 20110104464 | METAL-INFILTRATED TITANIUM-SILICON-CARBIDE AND TITANIUM-ALUMINUM-CARBIDE BODIES - Densified composites of a metal such as copper or aluminum with a titanium-silicon-carbide or titanium-aluminum-carbide ceramic material are prepared by forming the ceramic material into a body, and infiltrating the body with the molten metal. The metal is able to rapidly penetrate into void spaces, between grain boundaries and even into the crystal structure of the ceramic grains to form a composite. The starting ceramic material may be previously densified, in which case various types of gradient structures can be produced easily. The process can be operated at low pressures, and so the hot pressing methods that normally must be used to densify these ceramic materials can be avoided. | 05-05-2011 |
| 20110132230 | GEOPOLYMER PRECURSOR DRY MIXTURE, PACKAGE, PROCESSES AND METHODS - The present invention generally relates to a geopolymer precursor dry mixture, geopolymer precursor package, a process of preparing a geopolymer composition, and a method of providing a geopolymer composition to a geopolymer composition preparation site. | 06-09-2011 |

| 20110166018 | Method for Making Porous Acicular Mullite-Containing Composites - Porous composites of mullite and cordierite are formed by firing an acicular mullite body in the presence of a magnesium source and a silicon source. In some variations of the process, the magnesium and silicon sources are present when the acicular mullite body is formed. In other variations, the magnesium source and the silicon source are applied to a previously-formed acicular mullite body. Surprisingly, the composites have coefficients of linear thermal expansion that are intermediate to those of mullite and cordierite alone, and have higher fracture strengths than cordierite at a similar porosity. Some of the cordierite forms at grain boundaries and/or points of intersection between mullite needles, rather than merely coating the needles. The presence of magnesium and silicon sources during acicular mullite formation does not significantly affect the ability to produce a highly porous network of mullite needles. | 07-07-2011 |
