METHOD OF PRODUCING OF COMPOSITE CERAMIC PRODUCTS Russian patent published in 2017 - IPC C04B35/81 C04B35/117 C04B35/645 

FIELD: machine building.

SUBSTANCE: invention can be used to produce composite ceramic products of support element type (for example, rings/shafts of roller/journal bearings) or tools in form of cup-tip tools or cutting ceramic plates. A method of producing of the composite ceramic products includes preparation of an initial charge comprising a powder matrix Al₂O₃, threadlike reinforce crystals of silicone carbide and viscous binding substance, formation by extrusion from the initial charge of a flat billet with orientation of the threadlike reinforce crystals in direction of the extrusion, forming from the billet of a briquette in viscous-flow state, stripping of the binding substance from the briquette and hot pressing of the product. To form a cylindrical briquette the flat billet in the viscous-flow state is wounded on the mandrel, during the binding substance stripping the briquette axis has a vertical position, the hot pressing of the product is performed in the direction of axis of the cylindrical briquette.

EFFECT: expansion of the process abilities of the method and increased crack strength of the products.
