Abstract
The present disclosure provides a method for determining free radicals of CaO—AlOseries oxide melts. The method includes dividing the CaO—AlOseries oxide powder to into two aliquots by mass, putting into two identical corundum crucibles and tamping. The method also includes heating the two aliquots at the same high temperature in furnaces with and without a static magnetic field, respectively. Cylindrical samples with the same diameter and height, and only containing the melt at the bottom of the crucible and the slag reaction interface are drilled out from said two crucibles and ground into powder samples. The free radical relative content of the CaO—AlOseries oxide melts can be calculated from a ratio between the difference of the reaction mass contents of CaO in the two powder samples and the total mass content of CaO.
