GB/T 5069.11-2001 Chemical analysis of magnesia and magnesia-alumina refractory materials--Complexometric titration method for determination of calcium oxide and magnesium oxide content (English Version)
This standard specifies the methods for determining the amount of calcium oxide and magnesium oxide by EDTA complexometric titration, the determination of calcium oxide by EGTA complexometric titration, and the determination of magnesium oxide by CyDTA complexometric titration. This standard is applicable to the determination of calcium oxide and magnesium oxide in magnesia, magnesium-aluminum (aluminum-magnesium) refractory raw materials and products. The measurement range: the mass fraction of calcium oxide > 1.00%, and the mass fraction of magnesium oxide > 2.00%.
