RAW MATERIAL COMPOSITION FOR THE PRODUCTION OF CHEMICALLY RESISTANT MATERIAL FIBER AND THIN FILMS Russian patent published in 2021 - IPC C03C13/02 C03C13/06 

FIELD: mineral fibers and thin films production

SUBSTANCE: invention relates to the field of production of mineral fibers and thin films based on rocks. It can be used in equipment producing continuous fibers and thin films with a diameter of 6 to 40 microns or a thickness of 1 to 20 microns. A fiber or a thin film based on rocks and natural minerals, has chemical composition containing the following components in wt%: aluminum oxide 6.0-10.0, a mixture of iron oxides 8.0-10.0, titanium oxide 1.5-3.0, calcium oxide 7.0-9.0, magnesium oxide 3.0-5.0, potassium oxide 1.5-3.0, sodium oxide 2.5-5.0, manganese oxide 3.0-5.0, zirconium oxide 5.0-8.0, zinc oxide 2.0-4.0 and silicon oxide - the rest. The components of the mixture are pre-crushed, mixed to a homogeneous composition, with a particle size of less than 100 microns. By mechanical activation, the initial components are transferred from the crystalline state to an incomplete amorphous state with a simultaneous process of ion-exchange reactions between the components and subsequent melting, producing the finished product.

EFFECT: increasing the chemical resistance of a mineral fiber or a thin film.
