Zusammenfassung: | FIELD: physics. ^ SUBSTANCE: present invention pertains to mineral fibre with microporous or mesoporous mineral coating, as well as an article with specific surface area which is at least equal to 10 m2/g and containing such fibre and possibly an organic component, such as a binding substance. The method of obtaining fibre with such coating involves bringing the fibre without coating into contact with a composition, containing binding organic groups, and at least one precursor substance, which is part of the coating, and polymerisation of the precursor substance around the binding organic groups with subsequent removal of the binding organic groups. The fibre with coating is used during catalysis, photocatalysis, filtration and treatment of gases and liquids, as well as at high temperatures, for example 900C or higher, due to its remarkable stability under such conditions. ^ EFFECT: obtaining fibre with good mechanical properties and large specific surface area. ^ 14 cl, 4 ex, 5 tbl |
