摘要：
A process for sealing a ceramic filter by infiltrating a metal into an end of the filter. The process includes the steps of contacting the end of a porous ceramic filter with a molten metal, whereby the metal enters into the ceramic matrix to substantially fill the void space. The ceramic filter is cooled to form a filter having a ceramic-metal composite portion. The present invention also provides a filter having an infiltrated metal seal.
