    • n Silicate (Chem) A salt of silicic acid.☞ In mineralogical chemistry the silicates include; the unisilicates or orthosilicates, salts of orthosilicic acid; the bisilicates or metasilicates, salts of metasilicic acid; the polysilicates or acid silicates, salts of the polysilicic acids; the basic silicates or subsilicates, in which the equivalent of base is greater than would be required to neutralize the acid; and the hydrous silicates, including the zeolites and many hydrated decomposition products.

    • n silicate A salt of silicic acid. Silicates formed by the union of silicic acid with the bases alumina, lime, magnesia, potassa, soda, etc., constitute by far the greater number of the minerals which compose the crust of the globe. Glass is a mixture of artificial silicates of alkalis and alkaline earths or metallicoxids (see glass).
