초록

Porous monolithic ceramic support substrates, well suited for consolidating inorganic filtration membranes thereto, e.g., micro/ultrafiltration membranes, to provide composite inorganic micro/ultrafiltration devices, have a mean equivalent pore diameter Ds ranging from 1 to 20 m2 particles, wherein the percentage by weight of TiO2, with respect to the total weight of Al2O3 plus TiO2, ranges from 1% to 75%.

대표
청구항

A porous monolithic ceramic support having a mean equivalent pore diameter Ds ranging from 1 to 20 m30%, comprising ceramic alumina particulates at least partially coated with TiO2 particles, and wherein the percentage by weight of TiO2, with respect to the total weight of Al2O3 plus TiO2, ranges from 1% to 75%, the TiO2 being present in an amount which allows high porosity to be maintained in the support when the support is sintered at low sintering temperatures.
