Two common materials made of silica are glass and concrete. Glass is primarily composed of silica sand, which is melted and formed into various shapes, while concrete uses silica in the form of sand and gravel as aggregates mixed with cement. Both materials leverage the properties of silica for strength and durability in construction and various applications.

What photosynthetic have a glassy two part cell wall made of silica?
Diatoms are photosynthetic organisms with a glassy two-part cell wall made of silica. These cell walls, called frustules, have intricate patterns and are responsible for the diverse shapes and sizes of diatoms.
Is obsidian made of silica?
Not entirely, though it is rather rich in silica.
Are onecelled organisms with shells made of silica?
Yes, diatoms are one-celled organisms with shells made of silica. These shells are called frustules and are made up of two overlapping parts that fit together like a petri dish. Diatoms are a type of algae found in marine and freshwater habitats.
Is silica a plastic?
No. Silica is a mineral-forming substance.
How many covalent bonds are there in one molecule of Silica?
One molecule of Silica (SiO2) contains two covalent bonds: one between the silicon atom and the oxygen atom in the middle, and another between the silicon and each of the two oxygen atoms on the sides.
