To make a pure sample of silicon, one common method is the metallurgical process, which involves heating silicon dioxide (SiO2) with carbon in an electric arc furnace to produce metallurgical-grade silicon (MG-Si). This MG-Si can then be purified further through the chemical vapor deposition (CVD) method, where it is reacted with hydrogen chloride to form trichlorosilane (SiHCl3), which is then distilled and reduced to produce high-purity silicon. Another approach is the Siemens process, which involves the deposition of silicon from trichlorosilane onto heated silicon rods, resulting in highly pure silicon.

Compute the density of an 820g sample of pure silicon occupying a 350cm3 container?
Density is calculated as mass divided by volume. In this case, the mass of the silicon sample is 820g and the volume of the container is 350 cm^3. Therefore, the density of the silicon sample in the container is 820g / 350 cm^3 = 2.34 g/cm^3.
Why silicon is a pure substance?
Silicon is considered a pure substance because it is made up of only silicon atoms. It is a chemical element with a specific atomic structure and unique properties. In its pure form, silicon does not contain any other elements or impurities.
Why is pure silicon deliberately made impure again when it is used to make computer chips?
Silicon is essentially an insulator when pure. When generating wells or electron barriers, silicon is Doped with Boron, Phosphorus and Arsenic. The details of how this works can be found in numerous books on IC manufacturing.
What is a sample of SiO2?
silicon dioxide
What is the colour of silicon?
Pure silicon is gray in color and has a metallic luster
Is a silicon chip a pure element?
No, a silicon chip is not a pure element. A silicon chip is made up of silicon as well as other materials such as dopants and conductive metals to function as a semiconductor in electronic devices.
Is silicon dioxide a mixture or pure substance?
Silicon dioxide is a pure substance. It is a chemical compound made up of silicon and oxygen atoms in a fixed ratio, with a specific chemical formula (SiO2).
