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.
摘要翻译： 通过将陶瓷材料形成体内并用熔融金属渗透身体，制备诸如铜或铝的金属与钛 - 碳化硅或钛 - 碳化铝陶瓷材料的致密复合材料。 该金属能够迅速地渗透到晶界之间的空隙，甚至陶瓷晶粒的晶体结构中，以形成复合材料。 起始陶瓷材料可以预先致密化，在这种情况下可以容易地生产各种类型的梯度结构。 该方法可以在低压下操作，因此可以避免通常必须用于致密化这些陶瓷材料的热压方法。

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.
