LIMESTONE-SILICATE-PERICLASE CLINKER Russian patent published in 1997 - IPC

FIELD: refractory materials. SUBSTANCE: clinker has lime containing, wt. -%: magnesium oxide, 3-15; aluminium oxide, 1-1.6 ; and iron oxide, 0.5-1; magnesian-silicate component containing 40 wt.-% magnesium oxide, not less, and 6-12 wt. -% iron oxides and 0.5-1 wt.-% aluminium oxide at the following indices of clinker chemical composition, relative units: coefficient of silica saturation with lime f = 0.88-0.92; siliceous modulus determining the ratio of calcium oxide to magnesium oxide 1.3-4, and phosphorus oxide content at the range 0.15-1.0 wt.-%. Properties: opened porosity is 2.8-5.4%, refractoriness is above 1770 C, complete stabilization of dicalcium silicate. Maximal temperature at using is 1650-1700 C. EFFECT: improved quality and property. 3 cl, 2 tbl
