Chemical analysis of magnesite and dolomite refractory products (alternative to the X-ray fluorescence method). Apparatus, reagents, dissolution and determination of gravimetric silica | Status: Current, Confirmed

1 Scope This part of ISO 10058 specifies apparatus, reagents, dissolution and gravimetric silica analysis for the chemical analysis of magnesite and dolomite refractory products and raw materials. This part of ISO 10058 is applicable to the ranges of determination given in Table 1. ISO 10058 specifies procedures for the chemical analysis of magnesite and dolomite refractory products and raw materials within the ranges of determination given in Table 1. Table 1 — Range of determination (percentage by mass) Component Range Component Range SiO2 0,1 to 10 MgO 30 to 99,9 Al2O3 0,05 to 10 Na2O 0,01 to 1 Fe2O3 0,01 to 10 K2O 0,01 to 1 TiO2 0,01 to 1 Cr2O3 0,01 to 3 MnO 0,01 to 1 ZrO2 0,01 to 1 CaO 0,01 to 60 P2O5 0,01 to 5 LOI 0,01 to 60 — —
