CONTAINED IN VOL. 15.02, 2017 Outlines the chemical analysis of glass sands.

1.1 These test methods cover the chemical analysis of glass sands. They are useful for either high-silica sands (99% + silica (SiO )) or for high-alumina sands containing as much as 12 to 13% alumina (Al O ). Generally nonclassical, the test methods are rapid and accurate. They include the determination of silica and of total R O (see 11.2.4), and the separate determination of total iron as iron oxide (Fe O ), titania (TiO ), chromium oxide (Cr O ), zirconia (ZrO ), and ignition loss. Included are procedures for the alkaline earths and alkalies. High-alumina sands may contain as much as 5 to 6% total alkalies and alkaline earths. It is recommended that the alkalies be determined by flame photometry and the alkaline earths by absorption spectrophotometry.

1.2 These test methods, if followed in detail, will provide interlaboratory agreement of results.

Note 1-For additional information, see Test Methods C169 and Practices E50.

1.3 The test methods appear in the following order:

Procedures for Referee Analysis: Section Silica (SiO2)--Double Dehydration 10 Total R2O3--Gravimetric 11 Fe2O3, TiO2, ZrO2, Cr2O3, by Photometric Methods and 12-17 Al2O3 by Complexiometric Titration Preparation of the Sample for Determination of Iron 12 Oxide, Titania, Alumina, and Zirconia Iron oxide (as Fe2O3) by 1,10-Phenanthroline Method 13 Titania (TiO2) by the Tiron Method 14 Alumina (Al2O3) by the CDTA Titration Method 15 Zirconia (ZrO2) by the Pyrocatechol Violet Method 16 Chromium Oxide (Cr2O3) by the 1,5-Diphenylcarbo- 17 hydrazide Method Procedures for Routine Analysis: Silica (SiO2)--Single Dehydration 19 Al2O3, CaO, and MgO--Atomic Absorption Spectro- 20-25 photometry Na2O and K2O--Flame Emission Spectrophotometry 26-27 Loss on Ignition (LOI) 28

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
