However, only a small fraction (roughly 3 per cent on average) of the crustal abundance of most minerals exists in non-silicate form, as oxides, sulphides, or carbonates.
-
Lapis lazuli is an ornamental rock formed by the regional metamorphism of limestone; it has blue lazurite (sodium calcium aluminosilicate sulphate), white calcite, and pyrite as its main constituents.
-
Black smokers, debouching fluids at 350°C into the overlying sea water sit atop a mound of hydrothermal minerals, including sulphides, sulphates, oxides, and silicates.
-
The most significant user is the glass industry, which uses sodium carbonate to decompose silicates for glass making.
-
“Clay” as a mineral refers to a “cousin” of micas; that is, a silicate mineral containing structural sheets of silica tetrahedra tetrahedral arrangements of one Si and 4 Oxygen atoms, with the Oxygen atoms at the 4 corners.
Open thread: questions and explanations - The Panda's Thumb
-
Boric acid is also a constituent of certain silicates, such as tourmaline, axinite, and datholite.

-
Silicon is the second most abundant element in the Earth's crust, since most common rocks have crystalline frameworks made from silicon and oxygen: they are silicates.
-
Air-Krete is a magnesium silicate, cementitious (cement-based) insulation that is foamed and pumped into closed cavities.
-
- an absorbent clay (aluminum phyllosilicate) that has an astonishing number of industrial and medicinal uses, from the drilling and engineering industries, to a wide range of ceramics applications that include sand casting and rocket nozzles, to skin creams, laxatives and

Those are great glasses, borosilicate which is the same kind of glass as Pyrex lab glass which means it's stronger and can handle high heat and temperature shocks without cracking.
Oddities of the Klee Brasserie.
-
So it was with borosilicate glass, which had a considerably higher specific resistance than typical soda-lime glass.
-
When heated to magmatic temperatures, these clusters melt to form hydrosaline liquid that is immiscible with the silicate melt
Evidence for Fluid Saturation and Degassing
-
Zinc occurs in nature most commonly as sulphide (blende); it also occurs as carbonate (calamine) and silicate (smithsonite).

-
In the case of high-level waste, the nuclear industry has pioneered the stabilization of the liquid streams through vitrification into borosilicate glass blocks.
-
If the impact object was a stony carbonaceous chondrite there would be silicates all over the impact site.
-
Among the features, the silicate features from minerals like forsterite and enstatite ‘swamp’ the other features, ‘so our first job will be to understand’ the abundances of the silicates.
