Abstract
A high-temperature ceramic filter having a three-dimensional reticulated skeleton structure is prepared by applying a ceramic slurry to a synthetic resin foam having an open cell three-dimensional reticulated skeleton structure, followed by drying and firing. The ceramic slurry contains 20-40 parts by weight of aluminum titanate, 40-60 parts by weight of mullite, 2-20 parts by weight of alumina, and agalmatolite. The filter is useful for the filtration of molten metals.
