DIN EN ISO 21587-1-2007硅酸铝耐熔制品的化学分析(可选择X射线荧光法).第1部分:仪器、试剂、硅石的分解和重量测定

This part of ISO 21587 specifies reagents, dissolution and gravimetric silica analysis for the chemical analysisof aluminosilicate refractory products and raw materials.This part of ISO 21587 gives alternatives to the X-ray fluorescence (XRF) method given in ISO 12677:2003,Chemical analysis of refractory products by XRF -- Fused cast bead method.This part of ISO 21587 should be used in conjunction with ISO 21587-2 and ISO 21587-3, which give theanalytical procedures for the determination of the following:-- silicon(IV) oxide (SiO<(Index)2>)-- aluminium oxide (AI<(Index)2>0<(Index)3>)-- iron(III) oxide (total iron oxide calculated as Fe<(Index)2>0<(Index)3>)-- titanium(IV) oxide (TiO<(Index)2>)-- manganese(Il) oxide (MnO)-- calcium oxide (CaO)-- magnesium oxide (MgO)-- sodium oxide (Na<(Index)2>0)-- potassium oxide (K<(Index)2>0)-- chromium(III) oxide (Cr<(Index)2>0<(Index)3>)-- zirconium oxide (ZrO<(Index)2>)-- phosphorous(V) oxide (P<(Index)2>0<(Index)5>)

DIN EN ISO 21587-3-2007硅酸铝耐熔制品的化学分析(可选择X射线荧光法).第3部分:感应耦合等离子体和原子吸收光谱测定法

This part of ISO 21587 specifies inductively coupled plasma/atomic emission (ICP/AE) spectrometry andflame atomic absorption (FAA) spectrometry methods for the chemical analysis of aluminosilicate refractoryproducts and raw materials.The methods are applicable to the determination of the following:-- silicon(IV) oxide (SiO<(Index)2>)-- aluminium oxide (AI<(Index)2>0<(Index)3>)-- iron(III) oxide (total iron oxide calculated as Fe<(Index)2>0<(Index)3>)-- titanium(IV) oxide (TiO<(Index)2>)-- manganese(Il) oxide (MnO)-- calcium oxide (CaO)-- magnesium oxide (MgO)-- sodium oxide (Na<(Index)2>0)-- potassium oxide (K<(Index)2>0)-- chromium(III) oxide (Cr<(Index)2>0<(Index)3>)-- zirconium oxide (ZrO<(Index)2>)-- phosphorous(V) oxide (P<(Index)2>0<(Index)5>)This part of ISO 21587 gives alternatives to the X-ray flluorescence (XRF) method given in ISO 12677:2003,Chemical analysis of refractory products by XRF -- Fused cast bead method.
