Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 703-2009 "Determination of X-ray fluorescence spectrometry limestone CaO, MgO, SiO2 content", and this standard
YS/T 703-2009 compared to the main technical changes are as follows.
--- Determine the melting method is a method, tableting method to method two;
--- In a method of increasing the determination of iron, aluminum, potassium content;
--- Determine the analytical measurement range of the method of the elements and allow poor.

Methods for chemical analysis of limestone measuring element content
X-ray fluorescence spectrometry
1 Scope
This standard specifies a method of calcium, magnesium, silicon, iron, aluminum, potassium content determination of molten limestone.
This standard specifies the method two, calcium, magnesium, silicon element content determination tableting limestone.
This standard is a method for the determination of elements in limestone content measurement range (expressed as the oxide) shown in Table 1.
This standard applies to method two limestone elements in the determination of the measurement range (expressed as the oxide) shown in Table 2.
Table 1
Element measurement range /%
CaO 42.50 ~ 55.80
MgO 0.20 ~ 10.70
SiO2 0.15 ~ 8.00
Fe2O3 0.050 ~ 0.30
Al2O3 0.12 ~ 0.40
K2O 0.04 ~ 0.20
Table 2
Element measurement range /%
CaO 41.0 ~ 65.0
MgO 0.30 ~ 11.30
SiO2 0.35 ~ 5.50
