FIELD: chemistry.SUBSTANCE: invention refers to compositions of broken colour glass for producing light-weight inorganic filling agents that are durable hollow glass microspheres of different grades used to create low-density multilayer construction materials for aircraft engineering, shipbuilding industry and vehicle manufacturing industry. The glass for producing colour glass contains the ingredients in the following proportions, wt %: NaO 8.00-20.00; BO8.00-15.00; CaO 4.00-10.00; ZnO 1.00-3.50; ZrO0.01-0.30; FeO0.01-0.50; TiO0.0-0.40; AlO0.0-1.00; SO0.50-1.50; CrO0.001-0.20; MoO0.001-0.20; SiOthe rest.EFFECT: producing the glass microspheres having a true density of 0,15-0,40 g/cmand high durability.1 tbl |
