No, quartz contains more silica than olivine. Quartz is made up of silicon dioxide (SiO2), which is about 46.7% silicon and 53.3% oxygen, while olivine is a magnesium iron silicate (Mg,Fe)2SiO4, containing less silica.
The mantle has less aluminum and less silicon than the crust does.
Quartz is a mineral, silicon dioxide, not a type of rock. Quartz is a constituent of many rocks, eg. granite, which is composed primarily of quartz, feldspar, and mica.
There are many elements less electronegative than silcon. Look at the periodic table, and pretty much everything (with a few exceptions) to the left of, and below silicon will be less electronegative.
The temperature sensitivity of silicon is less than germanium because silicon has a wider energy band gap than germanium. This wider band gap allows silicon to operate more efficiently at higher temperatures, resulting in less temperature-dependent changes in its electrical properties compared to germanium. Additionally, silicon has a higher thermal conductivity than germanium, which helps dissipate heat more effectively, reducing temperature effects on its performance.
Quartz consists of silicon and oxygen (2 times as many oxygen atoms than silicon atoms).
No, quartz contains more silica than olivine. Quartz is made up of silicon dioxide (SiO2), which is about 46.7% silicon and 53.3% oxygen, while olivine is a magnesium iron silicate (Mg,Fe)2SiO4, containing less silica.
Silicon carbide is a synthetic compound made from silicon and carbon, while quartz is a natural mineral made of silicon dioxide. Silicon carbide is harder and more durable than quartz, making it suitable for use in industrial applications like grinding and cutting tools. Quartz is widely used in jewelry and decorative items due to its clarity and appearance.
Aluminum is less electronegative than silicon.
The mantle has less aluminum and less silicon than the crust does.
No, quartz is not an ionic compound. Quartz is a mineral composed of silicon and oxygen atoms arranged in a continuous framework of SiO4 silicon-oxygen tetrahedra. It is a covalent compound rather than ionic.
No, there is no substitute for quartz (silicon dioxide) as it has several special properties that no other mineral has (e.g. transparent to both ultraviolet and visible light). However if you are just looking for a different mineral than quartz that can be used as a source of silicon for use in semiconductors and silicone oils and plastics, yes there are other silicon based minerals but they are more complex than quartz is chemically which sometimes makes extracting the silicon more difficult and expensive.

No, quartz and diamonds are not the same. Quartz is a mineral made of silicon and oxygen, while diamonds are made of carbon. Diamonds are harder than quartz and have different physical and chemical properties.
The mantle has less aluminum and silicon than the crust does.
No. Hematite (crystallized iron oxide) is 6.5 on the MOHS scale. Quartz (silicon dioxide)is 7.0.
