METHOD OF PRODUCING GLASS-CERAMIC MATERIAL Russian patent published in 2014 - IPC C03C10/12 

FIELD: chemistry.

SUBSTANCE: method of producing glass-ceramic material includes preparing an aqueous slurry of lithium-aluminosilicate glass, moulding workpieces in porous moulds, drying and firing. The workpieces are dried at temperature of 150°C for 2-3 hours, followed by saturation a solution of oligomethylphenyl spirosiloxane in acetone and firing at 1250°C for 2-3 hours.

EFFECT: reducing permittivity and firing shrinkage of the material to zero water-absorption values, while preserving other physical and processing properties at a high level.
