MIXTURE FOR MAKING CERAMIC BRICKS Russian patent published in 2025 - IPC C04B33/04 C04B33/135 

FIELD: ceramics.

SUBSTANCE: invention relates to production of ceramic wall articles and can be used in production of ceramic bricks. Ceramic mixture for making bricks includes loam of Buguruslansky deposit, wt.%: SiO₂ 59.24; Al₂O₃ 9.98; Fe₂O_3com 4.48; MgO 2.93; CaO 8.95; K₂O 1.70; TiO₂ 0.71; Na₂O 1.47; LOI 10.54, ash and slag wastes of Orsk TPP-1, wt. %: SiO₂ 31.57; CaO 4.04; MgO 1.34; Fe₂O_3com 3.93; Al₂O₃ 9.34; K₂O 1.01; TiO₂ 0.52; Na₂O 0.33; LOI 47.92 and silicate lump SiO₂ 72.39; Al₂O₃ 0.51; Fe₂O_3com 0.51; Na₂O 25.87; CaO 0.41; SO₃ 0.31 at the following ratio of components, wt.%: low-melting loam 65-75, ash and slag wastes of Orsk TPP 15-25, lump silicate 10.

EFFECT: high strength and reduced water absorption, which increases crack resistance of the raw brick during drying, provides the possibility of defect-free automatic loading and transportation of the dried semi-finished product, expands mineral-raw material base for production of ceramic bricks and colour gamut of finished products depending on quantity of introduced ash-and-slag wastes.
