18.3 Structure and General Properties of the Metalloids
Germanium is very similar to silicon in its chemical behavior. Arsenic and antimony generally form compounds in which an oxidation state of 3+ or 5+ is exhibited; however, arsenic can form arsenides with an oxidation state of 3−. These elements tarnish only slightly in dry air but readily oxidize when warmed.

MOISSANITE (Silicon Carbide)
Moissanite is a mineral that was first discovered in fragments of the meteorite at Diablo Canyon or Meteor Crater in Arizona. It was named in honor of its discoverer, Nobel Prize winner Dr. Ferdinand Henri Moissan. Synthetic moissanite is also known as silicon carbide after its chemistry and by the trade name, carborundum.In the meteoritic material, moissanite is associated with tiny diamonds.

What is the current price for a Kg of every element in the
This depends highly on the purity, and so price can vary by two orders of magnitude or more. For example, 99.9% pure silicon is cheap as dirt, but 99.99999999% pure silicon will cost you a pretty penny. They''re essentially the same thing for most chemical purposes, but only the latter can be used for semiconductor fabriion.
Silicon carbide (SiC) can be introduced to the matrix to improve the performance of C/C composites, because it increases the hardness and thermal stability, and decreases the chemical reactivity
