A number of other inorganic compounds of trace elements, such as barium silicofluoride CBaSiFg), sodium selenate (NaSeOi ) and thallium sulfate CTlaSOi ) have occasionally been used as insecticides, but their use is so limited, it cannot make any significant contribution to dispersion of trace elements in the soil. 

A woman administered to her 6-yr-old child and to herself undefined amounts of two products, one based on atrazine and the other on barium silicofluoride. The mother was found unconscious and recovered under intensive care. Her serious condition was attributed to the highly toxic... 

The different types of admixtures, known to reduce alkali-aggregate reactions, can be divided into two groups those that are effective in reducing the expansion due to the alkali-silica reaction, and those that lower expansions resulting from the alkali-carbonate reaction. For the alkali-silica reaction, reductions in the expansion of mortar specimens have been obtained with soluble salts of lithium, barium and sodium, proteinaceous air-entraining agents, aluminum powder, CUSO4, sodium silicofluoride, alkyl alkoxy silane,... 

Sulphates and Silicofluorides. — Dissolve 5 gin. of ammonium fluoride in a platinum dish in 25 cc. of water, and add 25 cc. of hydrochloric acid, followed by barium chloride solution. No turbidity should ensue.

IV.27 HEXAFLUOROSILICATES (SILICOFLUORIDES), [SiF6]2 Solubility Most metallic hexafluorosilicates (with the exception of the barium and potassium salts which are sparingly soluble), are soluble in water. A solution of the acid (hydrofluosilicic acid H2[SiF6]) is one of the products of the action of water upon silicon tetrailuoride, and is also formed by dissolving silica in hydrofluoric acid.

Among the anions, only silicofluorides interfere they react similarly to sulfates. The test solution must necessarily be neutral. When alkaline solutions are present, as when testing a sodium carbonate extract, it is advisable to acidify a few drops of the test solution with hydrochloric acid, evaporate to dr5mess on the water-bath, and then to add barium carbonate. After this treatment, the limit of identification is about double that with neutral solutions.
