| description | A structure for use in high temperature applications and including a porous ceramic material consisting essentially of about 50-90 percent by weight iron or magnesium stabilized aluminum titanate (AlTiO5) and about 10-50 percent by weight strontium feldspar (SrO.Al2O3.2SiO2), and having a coefficient of thermal expansion over a temperature range from room temperature to 1000° C. of about -10x10-7/° C. to +15x10-7/° C., a heat capacity at 500° C. greater than 3.2 J/cm3K, a porosity of about 15-50 percent by volume, preferably 40-50 percent by volume, and a median pore size of about 5-50 micrometers, preferably 8-15 micrometers. The structure is especially useful as a diesel exhaust particulate filter. |
