Summary:
This standard specifies the method for determining the amount of calcium oxide and magnesium oxide by EDTA complexometric titration, the amount of calcium oxide by EGTA complexometric titration, and the amount of magnesium oxide by CyDTA complexometric titration. This standard is applicable to the determination of the amount of calcium oxide and magnesium oxide in magnesia and magnesia-alumina (aluminum-magnesium) refractory raw materials and products. The determination range is: the mass fraction of calcium oxide is greater than 1.00%, and the mass fraction of magnesium oxide is greater than 2.00%.
