METHOD OF PREPARING PRODUCTS FROM SINTERED GLASS CRYSTALLINE LITHIUM ALUMOSILICATE MATERIAL Russian patent published in 2001 - IPC

FIELD: large-size ratio transparent products of intricate shape made of glass ceramic using ceramic methods, more particularly ceramic and aircraft industries, and still more particularly manufacture of radomes. SUBSTANCE: manufacture of products employs simple ecologically clean method of molding by slip casting from high density aqueous suspensions into porous shapes. Material is milled by using wet method to give slip having density of 1.97-2.05 g/cubic cm, milling fineness of 0.063 m g-15% at pH of 7.5-9.0. EFFECT: greater density of molded semiproducts, lower firing temperature and reduced shrinkage of products during firing operation. 2 tbl
