METHOD OF PRODUCTION OF CERAMIC ARTICLES Russian patent published in 2006 - IPC C04B35/19 C04B35/14 C03C10/12 

FIELD: production of ceramic articles.

SUBSTANCE: proposed method includes grinding the starting material by wet method for obtaining slip, stabilization of this slip, molding blanks from aqueous suspensions by slip casting method, thus forming porous gypsum molds; then heat treatment is performed; before heat treatment, surface of molded blank is treated with Cr₂O₃ at its concentration in water from 40 to 60 weight-%. Treatment of surface of molded blank with aqueous suspension of chromium oxide at concentration of from 40 to 60 weight-% increases blackness coefficient of blank, thus causing considerable activation of sintering process; number of technological operations and operating time are reduced considerably. Provision is made for use of rejects at molding stage.

EFFECT: enhanced efficiency.
