Correlation between chemical composition and alkali
1. Introduction. Bauxite-SiC composite refractories have been widely used in cement industry in China as the lining of transition zone for decades due to their excellent wear resistance and good thermal shock resistance [1], [2], [3], [4].Recently, plastics waste, tires and sewage sludge were applied as the alternative fuels of rotary kilns [5], [6], [7], [8].

Alumina and Alumina Refractories – IspatGuru
Refractories with 80 % and 85 % Al2O3 were originally developed for use in aluminum smelting and holding furnaces. It is rare that they find application in other types of furnaces. These refractories are based on calcined bauxite, as it is the closest mineral in Al2O3 content to their overall composition.
