摘要： An improved particulate filtration system has an inlet, for the fluid to be filtered, connected to a housing containing a filter medium such that the fluid passes through the filter medium, and an outlet for the filtered fluid to exit. The filtration system's improvement is the filter medium being comprised of a porous ceramic of fused platelet grains. In a particular embodiment, the porous ceramic is a celsian porous ceramic, where the celsian grains have a hexagonal morphology and display a continuous volume thermal expansion coefficient from 100°C to 1000°C.

摘要： A composite is formed by inserting a ceramic powder into a channel of a preform to form a ceramic powder filled preform. The ceramic powder has at least one reactive ceramic powder. The preform is a ceramic, ceramic-metal composite, metal or combination thereof that has walls that define a plurality of channels each channel having an opening at a surface of the preform. The ceramic powder filled preform is infiltrated with a molten metal to form the ceramic-metal body, which has at least one ceramic phase that is a reaction product of the reactive ceramic and molten infiltrated metal.

摘要： 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.
