Abstract: A porous ceramic body useful for making particulate filters is comprised of acicular mullite grains bound together by a ceramic grain boundary phase, wherein said porous acicular mullite body has a bulk carbon content from 0.005% to 10% by weight of the body. The porous body may be made by forming a mixture of mullite precursors (e.g., alumina and silica) and a compound that is inorganic carbon (graphitic or amorphous), inorganic compound that contains carbon (e.g., metal carbide) or an organic compound that decomposes to form inorganic carbon or an inorganic compound that contains carbon and heating in an atmosphere containing fluorine to form the acicular mullite body and removing the fluorine.

Abstract: Contacting a mixture of two or more porogens with a mixture used to prepare a ceramic body; wherein one of the porogens has a significantly different chemical property from that of at least one of the other porogens. The ceramic material is dried, and calcinated. The ceramic material must withstand the heat from the drying process and the calcining to become a sintered: (ceramic) body. By increasing the overall stability of the ceramic material the product yield is about 90% or greater.

Abstract: Skins and/or adhesive layers are formed on a porous ceramic honeycomb by applying a layer of a cement composition to a surface of the honeycomb and firing the cement composition. The cement composition contains inorganic filler particles, a carrier fluid and a clay material rather than the colloidal alumina and/or silica materials that are conventionally used in such cements. The cement compositions resist permeation into the porous walls of the ceramic honeycomb. As a result, lower temperature gradients are seen in the honeycomb structure during rapid temperature changes, which results in an increased thermal shock resistance.
Abstract translation: 通过将一层水泥组合物施加到蜂窝体的表面并焙烧该水泥组合物，在多孔陶瓷蜂窝上形成表皮和/或粘合剂层。 水泥组合物包含无机填料颗粒，载体流体和粘土材料，而不是常规用于这种水泥中的胶体氧化铝和/或二氧化硅材料。 水泥组合物抵抗渗透到陶瓷蜂窝体的多孔壁中。 结果，在快速温度变化期间，在蜂窝结构中可以看到较低的温度梯度，这导致耐热冲击性提高。

Abstract: The present invention relates to a process to reduce internal stresses in insulation molded onto complex pipes, preferably complex subsea pipe, to reduce cracking in the molded insulation. Insulation materials applies to complex pipes comprising branches, i.e., valves, and the like, may be susceptible to cracking at, or near where the branch connects to the pipe as the coating of insulation material cures or hardens. The process of the present invention aims to reduce post molded cracking by reducing molded in stress at the branch/pipe junction. This is accomplished by providing a preform at or near a branch/pipe junction prior to applying the coating of insulation material.
