Chemical analysis of chrome-bearing refractory products and chrome-bearing raw materials (alternative to the X-ray fluorescence method) - Apparatus, reagents, dissolution and determination of gravimetric silica1 Scope 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
