Thermal oxidation of 3C silicon carbide single‐crystal …
Thermal oxidation of thick single‐crystal 3C SiC layers on silicon substrates was studied. The oxidations were conducted in a wet O 2 atmosphere at temperatures from 1000 to 1250 C for times from 0.1 to 50 h.Ellipsometry was used to determine the thickness and index of refraction of the oxide films.

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..
