Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 21587-3 was prepared by Technical Committee ISO/TC 33, Refractories.
ISO 21587 consists of the following parts, under the general title Chemical analysis of aluminosilicate
refractory products (alternative to the X-ray fluorescence method):
⎯ Part 1: Apparatus, reagents, dissolution and gravimetric silica
⎯ Part 2: Wet chemical analysis
⎯ Part 3: Inductively coupled plasma and atomic absorption spectrometry methods

3 Determination of residual silica in solution by ICP/AES
3.1 Principle
The residual silica remaining in stock solutions (S1) or (S′1) is determined using ICP/AES.
3.2 Reagents
Prepare the reagents specified in ISO 26845 and ISO 21587-1 and the following.
3.2.1 Aluminium oxide solution, Al O 5 mg/ml.
2 3
Weigh 2,65 g of aluminium (purity, more than 99,5 % by mass, having Si, less than 0,001 % by mass) into a
platinum dish (e.g. 100 ml). Cover the dish with a watch glass, add approximately 100 ml of hydrochloric acid
(1+1) and heat on a steam bath in order to dissolve the metal. After cooling, dilute to 1 l in a volumetric flask
with water.
3.2.2 Matrix solution 1.
Transfer an appropriate aliquot portion of the aluminium oxide solution (5 mg/ml) into a 500 ml volumetric flask
and dilute to the mark with water. Prepare this solution freshly whenever needed.
NOTE The amount of the aluminium oxide solution to be used is determined by the chemical composition of the
sample. For example, use 35 ml for the aluminium oxide solution of a sample con
