Mineralogy. any of the largest group of mineral compounds, as quartz, beryl, garnet, feldspar, mica, and various kinds of clay, consisting of SiO 2 or SiO 4 groupings and one or more metallic ions, with some forms containing hydrogen. Silicates constitute well over 90 percent of the rock-forming minerals of the earth's crust.
Chemistry. any salt derived from the silicic acids or from silica.
The terrestrial planets are made of silicate minerals, which are oxygen-rich.
The formation of colloidal silica can be generated by acidification of silicate salts.
Heinz's group used mica, a silicate mineral that can be cleaved to produce smooth surfaces many microns across.
Most lava flows consist of basalt, which is a silicate.
Rather than silicate rocks, they'd have carbonaceous ones.
When they die they sink to the bottom of the reservoir, where the silicate remains.
Zircons--bits of zirconium and silicate that form in granite--are durable minerals.
They are too cool to have silicate clouds, but too warm for water clouds.
In silicate melts, water acts as a diluent and lowers the viscosity.
The older they are the darker they become because they get coated with darker silicate material from meteoroids.
British Dictionary definitions for silicate
a salt or ester of silicic acid, esp one of a large number of usually insoluble salts with polymeric negative ions having a structure formed of tetrahedrons of SiO4 groups linked in rings, chains, sheets, or three dimensional frameworks. Silicates constitute a large proportion of the earth's minerals and are present in cement and glass
