Overview

ISO 21587-1:2007 specifies the apparatus, reagents, dissolution procedures and gravimetric silica determination used for the chemical analysis of aluminosilicate refractory products and raw materials. Published as Part 1 of the ISO 21587 series, it provides a validated wet-chemical alternative to X-ray fluorescence (XRF) (ISO 12677:2003) for laboratories that perform classical chemical analysis. The standard defines preparation and standardization of solutions, fusion/dissolution techniques and the gravimetric determination of SiO2.

Key topics

Scope and purpose

Alternatives to the XRF fused bead method for aluminosilicate refractories.
Use in conjunction with ISO 21587-2 (wet chemical analysis) and ISO 21587-3 (ICP/AAS methods).

Apparatus and materials

Use of platinum crucibles, beakers, volumetric flasks and desiccators for high-temperature fusion and solution preparation.

Reagents and standard solutions

Detailed recipes and standardization methods for volumetric solutions (e.g., CyDTA, EDTA, zinc solutions).
Preparation of 1 mg/ml and dilute standard solutions for major oxides: SiO2, Al2O3, Fe2O3, TiO2, CaO, MgO, Na2O, K2O, Cr2O3, ZrO2, P2O5, MnO, etc.

Dissolution and fusion techniques

Sodium carbonate fusion for silica, acid digestion (including use of hydrofluoric and sulfuric acids) for refractory oxides, and procedures for preheating and ignition where required.

Gravimetric silica

Procedures for gravimetric determination of silicon(IV) oxide (SiO2) as a primary measurement approach in the absence of XRF.

Applications

Quality control and acceptance testing of aluminosilicate refractories in manufacturing and raw material supply chains.

Analytical laboratories requiring a certified wet-chemical procedure for reporting oxide compositions when XRF is unavailable or unsuitable.

Research and development for ceramics, refractories and high-temperature materials where precise oxide determinations (including gravimetric SiO2) are needed.

Regulatory compliance and certification that mandates traceable, standardized chemical analysis methods.
