Tóm tắt:
In this work, the influences of boric acid and high alumina cement used as modifying additives on the formation of CaO∙Al2O3 and CaO∙2Al2O3 were studied. Herein, commercially available chalk of the M-90 label and technical alumina of the G-0 label were utilized as initial raw materials. Heat treatment of powder mixtures with various concentrations of modifying additives was carried out in the temperature range of 1250-1350oC with an isothermal exposure times of 1h and 2h. It was found that the addition of additives into the raw mixture affected the ratio of target phases and the temperature interval of the phase formation of calcium-aluminate minerals.
