occupying the octahedral holes. Notice that the octahedral holes are along the edges (for a net of three cations) and in the center of the cube (one more cation). Thus we have four anions (FCC) and ...

The general formula is AB 2 O 4. The oxygens form an fcc lattice. The A cations occupy tetrahedral holes, and the B cation occupy octahedral holes. It then follows that 1/8 of the tetrahedral holes ...

Figure 1. This 1.30 ct Fancy brownish greenish yellow diamond contains an octahedral-shaped inclusion. Photo by Jian Xin (Jae) Liao. Primary diamond deposits are usually found in mantle-derived ...

In this article, we study the irregularity indices of the octahedral and icosahedral networks. These networks are used in crystallography, where the topology and structural aspects are carrying some ...
