  • Patent number: 9764991
    Abstract: Porous aluminum-containing ceramic bodies are treated to form acicular mullite crystals onto the surfaces of their pores. The crystals are formed by contacting the body with a fluorine-containing gas or a source of both fluorine and silicon atoms to form fluorotopaz at the surface of the pores, and then decomposing the fluorotopaz to form acicular mullite crystals. This process allows the surface area of the ceramic body to be increased significantly while retaining the geometry (size, shape, general pore structure) of the starting body. The higher surface area makes the body more efficient as a particulate filter and also allows for easier introduction of catalytic materials.

  • Patent number: 9321694
    Abstract: 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 highly porous particles through the support to deposit a layer of the highly porous particles of a ceramic or ceramic precursor onto wall(s) of the support and (b) calcining said deposited layer to form the discriminating layer. This method is an inexpensive and effective route to forming a discriminating layer onto the porous wall.
