Calculation of the refractoriness of kaolin


Refractoriness t (c) =[360+Al2O3-R2O]/0.228

Al2O3 is the mass percentage of Al2O3 in the sum of the results of SiO2 and Al2O3 analysis at 100; R2O is the mass percentage of the results of SiO2 and Al2O3 analysis with 100 other oxides.

The error of refractoriness calculated by this formula is within 50 C.
