Definitions
- 1
- : Mineralogy. any of the largest group of mineral compounds, as quartz, beryl, garnet, feldspar, mica, and various kinds of clay, consisting of SiO2 or SiO4 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.
Examples
We had been developing techniques to identify individual millimeter-size silicate crystals that contain only very small iron grains and have ideal recording properties.
A number of scientists and nonprofits have also researched the possibility of accelerating the processes by which various minerals—particularly those rich in silicate, calcium, and magnesium—pull carbon dioxide out of air or rainwater.
Our Goldilocks climate largely results from chemical reactions between carbon dioxide in the air and silicate minerals, which slowly reduces the level of the greenhouse gas in the atmosphere by burying it in sediments.
In this case, silicate in the ash melts as it hits the hot turbines of the engine and shuts it down.
He seemed to recall a state of lush, sybaritic softness, in pre-silicate times.
But there is no reason why, in these cases, the lead so employed should not be in the form of a fritted double silicate.
Soda-glass consists primarily of silicate of sodium with smaller quantities of silicate of aluminum and potassium.
A good method for the preservation of eggs is the use of sodium silicate, or water glass.
The well-known water-glass is a silicate of soda or potash dissolved in free or caustic soda, or potash.
