Describes methods for the chemical analysis of chrome-bearing refractory products and chrome-bearing raw materials, using traditional ("wet") methods, ICP-AES spectrometry and FAAS spectrometry.

This part of ISO 20565 specifies methods for the chemical analysis of chrome-bearing refractory products and chrome-bearing raw materials, using traditional (“wet??) methods, ICP-AES spectrometry and FAAS spectrometry. It covers apparatus, reagents, dissolution and determination of gravimetric silica. It is applicable in the ranges of determination given in Table 1. ISO 20565 provides alternatives to the X-ray fluorescence (XRF) method given in ISO 12677. Table 1 — Range of determination (% by mass) Component Range SiO2 0,5 to 10 Al2O3 2 to 30 Fe2O3 0,5 to 25 TiO2 0,01 to 1 MnO 0,01 to 1 CaO 0,01 to 3 MgO 15 to 85 Na2O 0,01 to 1 K2O 0,01 to 1 Cr2O3 2 to 60 ZrO2 0,01 to 0,5 P2O5 0,01 to 5 LOI −0,5 to 5 NOTE These values are after the loss on ignition (LOI) has been taken into account.
