Document Type and Number:
Japanese Patent JP4313708
Kind Code:
B2
Abstract:
This invention is directed to providing a high-performance ceramic support being capable of realizing early activation of a catalyst due to direct loading while maintaining the excellent properties of the substrate ceramic, and being less susceptible to heat deterioration, by specifying the kind and combination of optimal replacing elements and the replacing amount and the like. A ceramic support comprising a substrate ceramic containing Mg, Al, Si and O as constituent elements are solid-dissolved therein Ti and W as the second component. The proportion of cordierite crystal having solid-dissolved therein W and Ti is 25 mol % or more, whereby a high-performance directly supporting ceramic support is realized.
