Silicon dioxide is a compound, whereas diamond is an allotrope of carbon, a pure element.

Silicon substrate is essentially pure silicon, perhaps with some dopants added to alter its conducting properties. But, it’s a semiconductor. The oxide layer is silicon dioxide, which is a ceramic, so has no electrical conductivity.
Silicone substrate can be doped by adding other atoms to affect its conductivity. Silocon Dioxide is not affected [...]

Check halfway down for the ‘Monthly Publications’ section. Seems they only have until August of this year.
You might be able to find better statistics by looking for a specific type of silicon resource:
- 50% ferrosilicate
- 75% ferrosilicate
- silicon metal

Why does silicon dioxide melt at a very high temperature, when carbon dioxide is a gas at room temperature? Aren’t silicon and carbon in the same column, so shouldn’t they be related?
