METHOD OF MAKING CERAMIC ARTICLES Russian patent published in 2019 - IPC C04B35/19 C04B35/626 C04B33/28 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to ceramic and aircraft engineering, particularly, to production of ceramic articles for radio engineering. Disclosed method of producing ceramic articles involves grinding raw material of lithium aluminosilicate composition by wet method to obtain a slurry with density parameters, fineness of grinding, pH, moisture and viscosity, molding of articles by method of slip casting from water slurries into porous molds and thermal treatment. When preparing the slurry, grinding is controlled several times in the grinding process, wherein the sample of the slurry is dried after drying, and the presence of iron oxide Fe₂O₃, which is not included into the initial composition of the raw material, which enables to take rapid measures to prevent contamination of the slurry.

EFFECT: improved quality of ceramic articles due to exclusion of coloring impurities.
