FIELD: gamma-shielding materials; production of prefabricated blocks and facing tiles. SUBSTANCE: proposed glass ceramic feedstock comprises following components, wt. %: wastes and scrap resulting from optic glass production 88.0-92.0; clay 2.5-5.0; alumochromophosphate 1.0-1.9; syntanol 0.1-0.5, water 4.0-5.0. Resulting glass ceramic products have following physical and mechanical properties: average density 4.0-4. S g/cub.cm, compressive strength 120-180 MPa, gamma-radiation attenuation coefficient 0.29-0.31 cm. EFFECT: better protection against gamma-radiation. 2 tbl |
