METHOD OF PREPARING HIGH POROSITY CERAMIC MATERIAL

摘要

Contacting a mixture of two or more porogens with a mixture used to prepare a ceramic body; wherein one of the porogens has a significantly different chemical property from that of at least one of the other porogens. The ceramic material is dried, and calcinated. The ceramic material must withstand the heat from the drying process and the calcining to become a sintered: (ceramic) body. By increasing the overall stability of the ceramic material the product yield is about 90% or greater.
