摘要： A ceramic honeycomb wall-flow filter is prepared by plugging channels in a ceramic honeycomb comprised of clay by a method comprising the following. First, a mixture comprised of a dispersing liquid and ceramic powder is formed. Second, the mixture is inserted into at least one channel of a green ceramic honeycomb that is comprised of a clay to form a plugged green ceramic honeycomb wherein the dispersing liquid essentially fails to swell the clay. Alternatively, the mixture is inserted into a calcined ceramic honeycomb to form a plugged calcined ceramic honeycomb. Finally, the plugged green or calcined ceramic honeycomb is heated to a temperature sufficient to sinter the plugged green ceramic honeycomb to form a porous sintered plugged ceramic honeycomb. The method is particularly useful for simultaneously making the plugs and discriminating layers in the channels. In particular the method is useful to make wall-flow filter having plugs on at least one end with same composition as the discriminating layer or plugs on each end having different compositions.

摘要： The invention is a catalytic device comprised of a catalyst support of fused ceramic grains and a catalyst that is surface-bound to at least a portion of the ceramic grains, incorporated into at least a portion of the ceramic grains or combinations thereof, wherein the grains and catalyst form a surface structure that has a box counting dimension of greater than 1.00 or the box counting dimension has at least one step change when measured from a box size "d" of at least about 1 micrometer to at most about 1 millimeter. The invention is particularly useful in making a catalytic converter or catalytic converter-soot trap.

摘要： A mullite composition is comprised substantially of mullite grains that are essentially chemically bound wherein the composition h as at least two adjoining regions that have substantially different microstructures. The composition may be produced by forming a mixture of one or more precursor compounds having the elements present in mullite; shaping the mixture into a porous green shape applying a nucleation control agent to a portion of the porous green shape and then heating the porous green shape under an atmosphere and to a temperature sufficient to form the mullite composition.

摘要： A reaction product is made by flowing a liquid containing a reactant through a porous ceramic honeycomb wherein the porosity of the walls of the honeycomb are such that the liquid containing the reactant substantially penetrates into the walls and the reactant reacts as the liquid containing the reactant flows from the inlet end to the outlet end of the monolithic ceramic honeycomb.

摘要： A method of forming a porous mullite composition of acicular mullite grains having improved properties is described, where the mullite is formed at some time in the presence of a fluroine containing gas. For example, it has been discovered that improved properties may result from heating the mullite to a high temperature in an atmosphere selected from the group consisting of water vapor, oxygen, an inert gas or mixtures thereof or forming the mullite composition from precursors having an AL/Si ratio of at most 2.95.

摘要： A ceramic honeycomb wall-flow filter is prepared by plugging channels in a ceramic heoneycomb by a method comprising the following. First, a mixture comprised of a dispersing liquid and ceramic powder is formed. Next, the mixture is inserted on one end of the channel in an unplugged ceramic honeycomb such that the mixture flows to the other end where the mixture collects and forms a plugged ceramic honeycomb. Then, the plugged ceramic honeycomb is heated to a temperature sufficient to sinter the plugged ceramic honeycomb to form a porous sintered plugged ceramic honeycomb.

摘要翻译： 陶瓷蜂窝状壁流式过滤器通过以下方法将通道堵塞在由粘土组成的陶瓷蜂窝中而制备。 首先，形成由分散液和陶瓷粉末组成的混合物。 其次，将混合物插入至少一个由粘土组成的生陶瓷蜂窝的通道中，以形成堵塞的生陶瓷蜂窝，其中分散液实质上不会使粘土膨胀。 或者，将混合物插入煅烧的陶瓷蜂窝体中以形成堵塞的煅烧陶瓷蜂窝体。 最后，将堵塞的生坯或煅烧过的陶瓷蜂窝体加热至足以烧结堵塞的未烧结陶瓷蜂窝体的温度，以形成多孔烧结堵塞陶瓷蜂窝体。 该方法对于同时制作通道中的插头和识别层特别有用。 具体地说，该方法可用于制造在至少一端具有塞子的壁流式过滤器，其具有与识别层相同的组成，或者每端上的塞子具有不同的组成。
