|A general scheme has been worhed 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, A/20 3 ,
GaO and MgO by cornplexometry, Fe20 3 and Ti0 2 by polarography and
I l1e al/wlies by flame photometry. The analyt 1cal methods har1e been descrihed
in detail and the advantages and li mi tat ions of I he projHJsed scheme
hm1e been discussed.
