Is it possible to make a "silicon diamond?" : askscience

You got some good answers on a pure silicon "diamond", but if you follow that line of thinking slightly farther, you discover the most diamond- like material in the world- silicon carbide. It is the hardest abrasiveother than diamond, conducts heat faster than any crystalline solid except diamond, and if it is pure enough to be transparent, it is an excellent diamond simulant (Moissanite).
