METHOD OF PRODUCING CERAMIC PRODUCTS OF COMPLEX VOLUME FORM Russian patent published in 2018 - IPC C04B35/111 C04B35/634 B29C33/38 B33Y80/00 

FIELD: technological processes.

SUBSTANCE: method includes manufacture of a matrix, casting of a product by means of the matrix and heat treatment of the produced product. A 3D model is produced from the thermoplastic mass by additive moulding, immersed in a silicone mass to make a silicone shell, which is the product matrix. A heated ceramic slip is cast into the silicone matrix. The heat treatment of the product includes: preliminary sintering for 6 hours at a temperature of 300^oC with holding for 1 hour, then the heating is continued up to 1100^oC for 11 hours with holding for an hour, cooling and machining, after which the final sintering is carried out at 1450-1700^oC with holding for 1 hour in air for VK-95 and in vacuum for VK-94 to produce a ceramic product.

EFFECT: producing ceramic products of a complex volume form with high technical and functional characteristics.
