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： A porous discriminating layer is formed on a ceramic support having at least one porous wall by (a) establishing a flow of a gas stream containing agglomerates of particles and (b) calcining said deposited layer to form the discriminating layer. At least a portion of the particles are of a sinter-resistant material or a sinter-resistant material precursor. The particles have a size from 0.01 to 5 microns and the agglomerates have a size of from 10 to 200 microns. This method is an inexpensive and effective route to forming a discriminating layer onto the porous wall.

摘要： A ceramic honeycomb structure comprised of at least two separate smaller ceramic honeycombs that have been adhered together by a cement comprised of inorganic fibers and a binding phase wherein the smaller honey-combs and fibers are bonded together by the binding phase which is comprised of an silicate, aluminate or alumino-silicate. The fibers have a multi-modal size distribution in which some fibers have lengths of up to 1000 micons and other fibers have lengths in excess of 1 mm. The cement composition may be made in the absence of other inorganic and organic additives while achieving a shear thinning cement, for example, by mixing oppositely charged inorganic binders in water together so as to make a useful cement composition for applying to the smaller honeycombs to be cemented.
