Sintering and some properties of fine aluminosilicate ceramic, prepared on the basis of HCBS from broken porcelain electric insulator and pearlite, are studied. After firing at 1000 - 1500 C ceramic has open porosity of 1 - 8%, and ultimate strength in bending and compression of 45 - 65 and 350 - 500 MPa respectively. Compared with traditional fine ceramic materials, such as porcelain, semi-porcelain, hard faience, and majolica, in the new technology comparable properties are achieved with significantly (by a factor of 3 - 5) lower overall shrinkage and a reduced (by 150 - 200 C) firing temperature. Possible areas are indicated for implementingHCBS-technology in the field of production, not only for traditional fine ceramic, but also fine-grained structural, and artistic architectural ceramics. © 2013 Springer Science+Business Media New York.

Wet grinding in a disk mill is used to prepare highly-concentrated ceramic binder suspensions (HCBS) based on broken porcelain electric insulator and pearlite with a volume concentration of solid phase of 70% and with specified rheotechnological properties. Asemifinished product, obtained by slip casting and centrifugal molding, has original porosity of 20-22% and shrinkage during drying of less than 0.05%. © 2013 Springer Science+Business Media New York.
