METHOD OF PRODUCING MICRO- AND NANOPOROUS CERAMIC BASED ON ZIRCONIUM DIOXIDE Russian patent published in 2011 - IPC C04B35/486 C04B35/624 C04B38/00 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing a micro- and nanoporous ceramic and can be used in machine-building, chemical industry and power engineering to produce filter materials, catalyst supports and components of porous systems with special properties. The method of producing micro- and nanoporous ceramic based on zirconium dioxide involves preparation of a suspension of fine powder with a binding component, pouring the suspension into a mould, gelling and dehydrating the gel substance, drying and sintering the material. The gel substance is dehydrated by evacuation through a microporous substrate made from cordierite ceramic with micro- and nano-sized pore distribution. The microporous substrate determines the size and distribution of pores formed in the material.

EFFECT: obtaining a porous ceramic based on zirconium dioxide with given pore size.
