GB/T 5069.6-2001 Chemical analysis of magnesia and magnesia-alumina refractory materials--Chromazurol S photometric method for determination of aluminium oxide content (English Version)
This standard specifies the method for determining the amount of alumina by chrome azure S photometry. This standard applies to the determination of the amount of alumina in magnesia and magnesium-aluminum (aluminum-magnesium) refractory raw materials and products, and the measurement range is 0.10% to 2.00%. This standard does not apply to magnesia refractories with a mass fraction of titanium dioxide greater than 0.1%.
