Riassunto:The work is devoted to the current problem of creating high-strength ceramic materials using techno-genic waste. This problem is solved by using refractory clay as the main raw material component with the addition of high-iron calcium silicate steel slag in various proportions. The processes of phase formation that occur during heating of steel slag are considered. It has been established that the use of steel slag to produce ceramic materials is possible only if the destructive effect of dicalcium silicate formed in the slag at firing temperatures above 1000 °C is neutralized. This is possible due to the chemical transformation of dicalcium silicate into other calcium-containing minerals that are safe from the point of view of molded sample destruction, such as anorthite, wollastonite, gehlenite, and others that do not have polymorphism. Compositions of ceramic masses have been developed that ensure the production of high-strength anorthite ceramics (with water absorption from 2.8 to 13.4% and compressive strength of up to 200 MPa) for a wide range of purposes — structural (wall) building ceramics, clinker building ceramics, ceramic proppants, etc
