摘要: Highly porous acicular mullite bodies are prepared. A green body containing mullite precursors and a porogen is formed using a wet method. The green body is heated to sequentially remove any binder, the porogen and calcine it. The calcined body is mullitized. The process formed a calcined body that has excellent strength and can be handled easily. The mullitized body has very high porosity, small pores and has excellent fracture strength.

摘要: An improved catalyzed soot filter is comprised of a porous ceramic having, on at least a portion of the porous ceramic, an amorphous catalytic phase comprised of an alkali containing oxide glass having therein Si, Al or combination thereof. The improved catalyzed soot filter may be formed by contacting a porous ceramic such as mullite, silcon carbide or cordierite with an alkali containing compound that is a silicate, aluminate or alumino-siliicate and heating to a temperature sufficient to form an amorphous catalytic phase fused to at least a portion of the porous ceramic.
