Chemical analysis of magnesite and dolomite refractory products (alternative to the X-ray fluorescence method) -- Flame atomic absorption spectrophotometry (FAAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES)
This part of ISO 10058 specifies atomic absorption spectrometry (AAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) methods for the chemical analysis of magnesite and dolomite refractory products and raw materials.
It is applicable to components 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 | Na2O | 0,01 to 1 |
| Al2O3 | 0,05 to 10 | K2O | 0,01 to 1 |
| Fe2O3 | 0,01 to 10 | Cr2O3 | 0,01 to 3 |
| TiO2 | 0,01 to 1 | ZrO2 | 0,01 to 1 |
| MnO | 0,01 to 1 | P2O5 | 0,01 to 5 |
| CaO | 0,01 to 10 | — | — |
| LOI | 0,01 to 60 | — | — |
NOTE These values are after the loss on ignition (LOI) has been taken into account.
