The present invention relates to a SiC composite and a method for manufacturing the same. More particularly, the present invention relates to a slurry composition for ceramic matrix composites which can not only reduce the number of precursor impregnation pyrolysis (PIP) cycles but also be useful in the PIP process to increase hardness, thermal stability, and relative density.

The invention belongs to the field of eliminating pollutant gases. In particular, the invention belongs to the field of pollutant gas-absorbing material such as CO2, SO2, NOx and VOCs.

The present invention relates to a fresh composite or composite paste and a composite material comprising aggregates of recycled concrete, porous carbon, a binder and optionally water, as well as to the method for manufacturing the composite and the use thereof for sanitizing air (indoor or outdoor). The invention also relates to an article (for example, an anti-noise wall, a tunnel lining, an indoor decoration, an item of street furniture, etc.) comprising the composite according to the invention.

Composites of silicon and various porous scaffold materials, such as carbon material comprising micro-, meso- and/or macropores, and methods for manufacturing the same are provided. The compositions find utility in various applications, including electrical energy storage electrodes and devices comprising the same.

A base material for a membrane filter contains 90% by mass or more of aluminum oxide and 0.1% by mass or more and 10% by mass or less of titanium oxide. In a pore distribution curve measured by a mercury porosimeter, the base material has a first peak and a second peak which is higher than the first peak and is located at a pore size larger than that of the first peak, and the volume of pores with a pore size of 7 μm or more is 0.02 cm.sup.3/g or more.

Porous, binderless ceramic surface modification materials are described, and applications of use thereof. The ceramic surface material is in the form of an interconnected network of porous ceramic material on a substrate. The ceramic material may include a metal oxide, a metal hydroxide, and/or hydrates thereof, or a metal carbonate or metal phosphate, on a substrate surface. The substrate may be in the form of a metal or polymer particulate, powder, extrudate, or flakes.

Ultra-high temperature carbide (UHTC) foams and methods of fabricating and using the same are provided. The UHTC foams are produced in a three-step process, including UHTC slurry preparation, freeze-drying, and spark plasma sintering (SPS). The fabrication methods allow for the production of any kind of single- or multi-component UHTC foam, while also providing flexibility in the shape and size of the UHTC foams to produce near-net-shape components.
