It is not only on the basic substances upon which it acts, but also on the phosphoric and silicic acids, which it sets free.
This well-known substance is essentially a mixture of silicates with an excess of silica or silicic acid.
Oxide of cobalt in very small quantities yields, with silicic acid, an intensely blue silicate.
The minerals augite and hornblende are double salts of silicic acid, magnesium, and calcium with some ferrous oxide.
silicic chloride is a very voluble and strongly fuming gas, transparent and colourless, with an irritating and pungent smell.
silicic acid is not only indispensible to the growth of hair, but it forms a direct connection between blood and nerve tissues.
I knew that silicic acid, practically glass, was represented by sea-sand.
This method is particularly effective in the preparation of silicic acid.
silicic hardening does not begin till the full height is nearly attained.
The hydrate of baryta combines with the silicic acid, and forms the super-basic silicate of baryta, while the oxides become free.
