While the main chain of common organic synthetic polymers consists of repeating carbon (C) atoms, silicone is an "inorganic synthetic polymer" whose main chain is made of polysiloxane, which is the repetition of silicon(Si) and oxygen(O) atoms(1,2). ...

The production of silicon ferroalloys uses carbon to remove the oxygen from silica, releasing carbon dioxide in the process. The high temperatures needed in our furnaces also consume a lot of energy. But we’re committed to doing what we can to reduce this CO₂ footprint, by increasing the...
In minerals,the elements combine in the same, ordered arrangement every timethat mineral forms. For example, everyquartzmineral has the same arrangement of silicon and oxygen (silica) inside. Inclusionsthat sneak in during formation can create different colored versions of the same mineral. For quar...
Essentially, silicone is produced by the combination of an inorganic silicon and oxygen backbone with organic side groups that attach to the silicon atoms. The number of links or attachments between the organic and inorganic components is what determines the final consistency of the product. Various...
Silicon appears more commonly in the form of a compound such as silica (SiO2), where it is combined with oxygen, that usually takes the form of sand. Compounds can be treated to release the bound silicon, or used as they are to take advantage of the unique properties of the compound. ...
What is the density of paraffin? How many protons, neutrons, and electrons does silicon have? What is propane's density? A computer chip contains 1.20 \times 10^{23} atoms of silicon. What is its mass? What is the density of oxygen?
