METHOD FOR PRODUCING ARTICLES FROM GLASS-CERAMIC MATERIAL OF LITHIUM ALUMINOSILICATE COMPOSITION Russian patent published in 2022 - IPC C04B35/19 C03C10/12 C04B35/626 

FIELD: technological processes; radio engineering.

SUBSTANCE: invention relates to production of ceramic articles for radio engineering purposes, such as a shell of a head antenna fairing of high-speed rockets. Disclosed is a method of producing articles from a glass-ceramic material of a lithium aluminosilicate composition, which includes grinding pre-crystallized glass by a wet method to obtain a highly concentrated slurry, molding articles and their thermal treatment, where before grinding pre-crystallized glass by wet method, performing dry grinding of glass granulate in amount of 30–50% of total weight of glass for 0.5–1 hour, calculated amount of distilled water is introduced in one step and wet grinding is carried out for 2.5–4.5 hours, then glass is loaded in amount of 25–35% of the total weight of the glass and ground for 2.5–4.5 hours, glass is loaded in amount of 25–35% of the total weight of the glass and ground to a slurry with density of 2.10–2.15 g/cm³, fineness T₆₃=5.0–8.0% and content of particles with size less than 5 mcm 27–40%.

EFFECT: reduction of labor intensity of slurry manufacturing and duration of technological cycle of articles production.
