Overview

EN ISO 21587-1:2007 (CEN adoption of ISO 21587-1:2007) defines the apparatus, reagents, dissolution procedures and gravimetric silica determination used in the chemical analysis of aluminosilicate refractory products and raw materials. It provides a wet-chemical alternative to X-ray fluorescence (XRF) methods (see ISO 12677:2003) and forms Part 1 of the ISO 21587 series. The standard complements Parts 2 (wet chemical analysis) and 3 (ICP and atomic absorption spectrometry).

Key topics and requirements

Scope and purpose: Specifies reagents, dissolution techniques and the gravimetric method for SiO2 determination as part of alternative chemical analysis routes for aluminosilicate refractories.

Reagents and standard solutions: Detailed preparation and standardization procedures for key reagents and calibration standards, including:

CyDTA and EDTA volumetric solutions for complexometric titrations.
Zinc standard solutions (0.05 and 0.02 mol/l) for standardization.
Standard oxide solutions for Al2O3, CaO, Cr2O3, Fe2O3, MgO, MnO, P2O5, K2O and others at defined concentrations (typically 1 mg/ml and specified dilutions).

Dissolution procedures: Guidance on sample dissolution prior to analysis (acid treatments and controlled heating as necessary) to ensure quantitative recovery of analytes for subsequent determination.

Gravimetric silica determination: Procedures for isolating and weighing silicon(IV) oxide (SiO2) by gravimetric techniques as the primary SiO2 quantification route in this part.

Normative references and quality framework: References ISO 21587-2, ISO 21587-3 and ISO 26845 (general requirements for wet chemical, AAS and ICP methods) for method validation, calibration and laboratory practice.

Applications and users

Refractory manufacturers conducting raw-material acceptance and product quality control.

Analytical laboratories performing accredited chemical analyses as alternatives to XRF.

Materials scientists and R&D teams needing reliable SiO2 and oxide composition data for aluminosilicate products.

Quality assurance and compliance officers ensuring consistent test methodology across plants and countries.

Practical uses:

Routine QC of bricks, monolithics and raw refractories.

Verification of XRF results or where XRF is unavailable.

Support for compositional control in production, failure analysis and specification compliance.
