SUBSTRATE WITH ANTIMICROBIAL PROPERTIES Russian patent published in 2010 - IPC C03C17/36 C23C14/34 C23C14/06 

FIELD: construction.

SUBSTANCE: invention relates to an antimicrobial substrate (glass ceramic or metallic) for which at least one of the surfaces is coated with at least one mixed layer deposited in a vacuum with magnetic amplification. This layer contains at least one antimicrobial agent in amount of 2-1000 mg per m² of the substrate, mixed with binder material selected from oxides of metals, oxynitrides, oxycarbides or nitrides. The antimicrobial agent is silver, copper or zinc. This substrate possesses antimicrobial properties, particularly bactericidal activity, even without thermal treatment. If tempered or antimicrobial glass is required, a method for combined deposition of the antimicrobial agent and binder material can be used while using one or more metal targets followed by annealing. Antimicrobial properties are retained even after annealing. If necessary, a sublayer for blocking migration of the antimicrobial agent during annealing can be deposited on the surface of the substrate before the deposition step.

EFFECT: cheap production of a substrate having antimicrobial properties.
