  • Ceramic filter for a dust-containing gas and method for its production
    Patent number: 5198006
    Abstract: A ceramic filter for a dust-containing gas, which comprises a filter base having an average pore size of from 20 to 100 .mu.m, and a filter layer having an average pore size of from 0.2 to 10 .mu.m fixed at least to the filtering side surface of the filter base so that the filter layer fills the pores open on the surface of the filter base.
    Type: Grant
    Filed: August 16, 1991
    Date of Patent: March 30, 1993
    Assignee: Asahi Glass Company, Ltd.

  • Multicellular monolithic ceramic body and preparation thereof
    Patent number: 4327188
    Abstract: A multicellular monolithic ceramic body having many gas passages partitioned by thin walls is made of aluminum titanate as a major cnstituent and has less than 0.15% of a thermal expansion coefficient at 1000.degree. C. and higher than 350 kg./cm.sup.2 of a compressive strength as zero of an open frontal area as the properties in the direction along the gas passages and more than 35% of a porosity.
