METHOD FOR MANUFACTURING CONTAINERS FOR HEAT TREATMENT OF LOOSE MATERIALS Russian patent published in 2020 - IPC C03C10/12 B28B1/26 C04B35/14 

FIELD: technological processes.

SUBSTANCE: invention relates to production of containers for thermal treatment of loose materials, for example, for crystallization of amorphous glass of lithium-aluminosilicate composition. Disclosed is method of making containers for heat treatment of bulk materials, including grinding of crystallized glass, or rejected by heat treatment of articles or casts of an arbitrary shape, obtained from slurries remaining in makeup containers of molding sets after finishing collection of glass-ceramic articles by wet method to obtain an aqueous slip with density of 2.10–2.20 g/cm³, fineness of grinding with residue on 0.063 mm sieve 7.1–12.5 %, molding blanks in gypsum molds, drying and heat treatment, heat treatment of molded blanks is carried out at 800–1,100 °C during 0.5–2 hours.

EFFECT: technical result of the invention is to reduce labor intensity when manufacturing containers for heat treatment of granular materials.
