CERAMIC PRODUCTS AND THEIR PRODUCTION METHODS Russian patent published in 2021 - IPC C04B35/532 C04B38/00 B33Y10/00 B33Y40/20

Abstract RU 2753304 C2

FIELD: ceramic production.

SUBSTANCE: invention relates to a method for producing a ceramic product obtained from a ceramic structure created by 3D printing technology, which can be used as a ceramic filter for filtering melted metal. The method includes carbonization of the ceramic structure created by 3D printing technology, which includes impregnation and/or coating of the ceramic structure created by 3D printing technology with carbon precursor, or printing the ceramic structure according to 3D printing technology using ceramic printing medium containing carbon precursor. The appearing ceramic structure is subjected to pyrolysis to form a network of carbon connections inside the surrounding carbon structure created by 3D printing technology.

EFFECT: reducing shrinkage and deformation of products, which leads to reducing a risk of crack formation.
