An insulation material which is substantially free of fibers and which has a density of less than about 2.5 g/cc and a thermal conductivity of less than about 5 W/Km is formed from a composition comprising at least about 2%, by weight, carbon. The insulation material is resistant to thermal shock and is easily machined.

Compositions for and synthesis of improved insulations

A modular filter for removing particulate matter from gases or liquids is disclosed. The filter includes at least two porous ceramic or ceramic composite modules and a heater structure for regenerating the modules by heating which is integral with the modules. The regenerating structure may also be a ceramic structure. The filter modules may be manufactured using micropyretic synthesis and manufactured to have interconnected porosity. The filter may be used to remove particulates from the exhaust of engines such as engines of land and water vehicles.

Modulated and regenerative ceramic filter with insitu heating element

A modular membrane filter for gases liquid and particulate matter is disclosed, the filter comprising at least two porous ceramic or ceramic modules. A regenerative filter is also disclosed comprising a means for filtering; and a means for regenerating said means for filtering, said means for regenerating being integral with said filtering means.
