METHOD OF FABRICATING HIGH-DENSITY LITHIUM-ALUMINOSILICATE GLASS-BASED AQUEOUS SLIPS Russian patent published in 2003 - IPC

FIELD: ceramics. SUBSTANCE: invention is designed for fabricating glass-ceramic articles such as streamlined antenna covers, glass-forming machine shafts, etc. using slip casting in porous molds technique. In particular, raw material is loaded into mill together with alumina grinding bodies at ratio 1: (3-4). Dry grinding for 30-60 min is followed by adding water, wet grinding for 2-3 h, stabilizing slip by mechanical agitation, and adding hydrochloric acid or ammonium chloride in amounts 1.0-2.0 ml per 1 l slip. Raw material is utilized in the form of finely crushed glass or article production waste obtained after molding of blanks. EFFECT: simplified technology, reduced blank molding time, lowered amount of refuse, and reused waste. 2 cl, 2 tbl
