FIELD: chemistry.
SUBSTANCE: invention relates to fine ceramic technology and can be used in making ceramic products for various purposes. The ceramic slip preparation method involves preliminary thermal treatment of clay material with quarry moisture through hydrothermal treatment in an autoclave at saturated vapour temperature of 168-250°C for 3-60 minutes with an accelerated mode of raising and decreasing vapour pressure, preparation of the slip through wet grinding, moulding, drying and roasting. The accelerated mode of raising vapour pressure is achieved by releasing vapour from a used autoclave with stabilised material into an autoclave with already loaded starting material.
EFFECT: increased strength, reduced water absorption and density of products.
