A METHOD OF PRODUCING A CERAMIC FILTER AND A CERAMIC FILTER MEMBRANE

摘要

Herein is described a method of producing a ceramic filter and a ceramic filter membrane. The method includes providing a porous ceramic structure comprising a porous ceramic structure front layer, providing a slurry comprising oxide and/or 5 hydroxide ceramic particles, coating the slurry of ceramic particles onto at least a first surface portion of the ceramic structure front layer without the slurry fully penetrates the porous ceramic structure, drying the coated ceramic structure and calcination the ceramic particles to form a membrane layer. The ceramic structure front layer comprises sintered non-oxide ceramic material. The ceramic filter is advantageously 10 the filter is a monolithic filter.
