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

1.1These test methods cover the chemical analysis of glass sands. They are useful for either high-silica sands (99 % + silica (SiO2)) or for high-alumina sands containing as much as 12 to 13 % alumina (Al2O3). Generally nonclassical, the test methods are rapid and accurate. They include the determination of silica and of total R2O3  (see 11.2.4), and the separate determination of total iron as iron oxide (Fe2O3), titania (TiO2), chromium oxide (Cr2O3), zirconia (ZrO2), 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.

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

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