Abstract
A general scheme has been worked out for rapid and accurate analysis of a wide variety of silicate material such as sand, felspar, clay, bauxite, glass, etc. Silica has been estimated by a modified silico-fluoride method, Al2O3, CaO and MgO by complexometry, Fe203 and TiO2 by polarography and the alkalies by flame photometry. The analytical methods have been described in detail and the advantages and limitations of the proposed scheme have been discussed.
