METHOD FOR PRODUCING CARBON-CONTAINING CERAMIC MATERIAL Russian patent published in 2023 - IPC C04B35/488 C04B35/626 B82Y40/00 

FIELD: ceramic composite materials.

SUBSTANCE: invention relates to the producing ceramic composite materials, namely to methods for producing carbon-containing composite materials with an oxide matrix, and can be used in electrical engineering and various branches of mechanical engineering. The method includes preparing a water-based suspension from ceramic powder and a water-soluble polymer with the addition of a surfactant and multi-walled carbon nanotubes, casting into a mould, gelation, drying and sintering. During the process of casting into a mould and gelation, the suspension is exposed to a constant magnetic field with an induction of 5-10 mcT, and sintering is carried out using the spark plasma sintering method with the ability to maintain the orientation of carbon nanotubes.

EFFECT: production of a material with a stable phase composition and microstructure.
