COLOURED SLAG-STONE CAST PRODUCT AND MIXTURE FOR MAKING SAID PRODUCT Russian patent published in 2012 - IPC C04B32/00 C03C10/06 

FIELD: chemistry.

SUBSTANCE: invention relates to production of glass ceramic materials and stone-cast articles, and can be used in production of decorative, facing materials and art objects. The coloured slag-stone-cast product contains the following components, in wt %: SiO₂ - 33.0-39.2; AlO₃ - 6.7-10.5; CaO - 12.8-20.6; MgO - 3.9-7.6; FeO - 0.5-1.2; TiO₂ - 8.3-8.6; MnO - 0.1-0.3; V₂O₅ - 0.06-0.1; P₂O₅ - 0.6-1.1; Na₂O+K₂O - 4.8-8.4; B₂O₃ - 4.8-8.4; NaF+KF - 0.8-1.4. The mixture for producing a coloured slag-stone-cast product contains the following components, in wt %: blast-furnace slag 30-60; dehydrated slip wastes from enamel production 40-70.

EFFECT: wider raw material base for producing decorative stone-cast objects, which significantly reduces the cost of the stone-casting process.
