compares favorably with materials used in metallurgical enterprises, due to the high content of CaO and MgO;

has improved characteristics, as contains an increased amount of aluminum metal;

contributes to the preservation of the lining of the bucket;

is a substitute for aluminothermic, magnesian flux and partially deoxidizing agent at the same time.
