Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry.
Each unit cell consists of 8 atoms in a bravais lattice arrangement. This makes pure silicon highly stable at room temperature when compared to other materials like Germanium. Thus, pure silicon is least affected by water, acid or steam. Also, at higher 4.

The Figure shows the DC unit cell. If you first ignore the nuered atoms, the remainder form an FCC lattice; the atoms nuered 1-4 are then additional atoms loed in half of the tetrahedral interstitial spaces. As the tetrahedral hole is far too small to accommodate a full-sized atom, the others are pushed further apart, lowering the density.
